Di Filippo Exhausts

[Juchno]

Just want to tell everyone that Di Filippo make the best exhausts around.
Got on on my Ve ssv, a 3"a.
Best sounding exhaust system ever.
No Drone just pure 6.0L of sound

Thanks to this and, MAFless air and a retune I now have 280rwkw.
Loveing life.
Not quite enough power though, so its booked in for a 3:7's and a cam.
Should be quite nice.

So if you have the $$$$ Di Filippo all the way.

No XForce

[Clubb'N]

Glad to hear you're happy with the upgrade. :goodjob:

The comment about Di Filippo being the best sounding exhaust system ever is totally personal preference though. Don't get me wrong, I'm not bagging the quality, but personally I don't like their sound.
Just my 2c.

[macca33]

Good to see that you're happy Juchno.

Got any pics/specs of your car?

cheers

[EddieVE06]

For someone who isn't up there with exactly how a difilippo sounds vs an xforce, what makes the difi so different.
Ta

Oh, and what sort of damage $$ is the difi for a catback

[scott w]

i rang darren friday i think his prices are $4100 for a full system with duel 3" $2200 for a 3" cat back and $1800 for a 2 1/2 cat back in stainless i think there is somewhere in melbourne doing better prices on his systems

Yeah thats what he told me also but those prices do not inc fitting he said it'll be an extra couple of hundred & bout 4-6 hours depending on how busy he is, another interesting thing ive found out is that the twin 3" catbacks for ve's dont directly bolt up & do require mods to fit if running the stock cats.

scott w - speak to hp-f i ordered mine thru them @ a good price which includes fitting.

[VZMY06SS]

Does anyone know if di fillippo 1 7/8th headers have the same outlet sizing as the 1 3/4's? I am guessing that they are both 3 inch, but I would like confirmation.

Christ thats some $$$$

From memory pacies 1 7/8($650 great price made in adelaide), 3" ballistic cats($430) and 3" xforce $890 = $1970. Welder by trade so fitted myself

Add russo otr and tune and still under $4000

Love the sound and pulled 317rwkw's after cam install(at 2000km's)

Sounds like a very happy Customer:goodjob:

[ebbett21]

be great if DF made a twin 3'' in mild steel they S/S so damm expensive:bawl:

[MJR-57T]

I was going full difilippo system with the 2 1/2" into 3" and his cat pipes for $2300 to my door.
Ive read so many good reviews about his gear
Since then found out that the single 2 1/2 into 3" is too small and his cats arn't the best on the market (but by far not the worst either)

So CHE is doing a full 4-1 pacies, 100 cpi cats and twin 2 1/2 system fitted for $2400 drive away
Reason for the 2 1/2" instead of 3" is apparently 3" is too big to clear the diff and im lowering the tray so it will be even more tight

I dont know what DF charges to fit?

There is no doubt that DF make top quality exhausts, there are some knockers on here, but their just that ............. knockers. :bash:

I heard a twin 3" DF on a VE a couple of years ago, and while it sounded awesome, it was very loud, especially when compared to their earlier VT-VZ 3" systems.

Please post a sound file/video if you can some time, I'd like to hear it.

Cheers:)

[-GTS-]

+ 1 here for Di Fillipo!!

I love mine, not too loud, not too quiet - just right (for me anyway) :goodjob:

[smokey777]

all i can say is ya better love it for the price of the diffilipo

[Lincoln87]

$1500??

and i think a member on here was selling his for $1300. maybe. not sure.

Steve

Yes mate,their both 3" (76mm).

[MJR-57T]

i got onto darren about his DF 2 1/2 into 3" one tonner system sold on ebay.
Was going to buy it if his system was a little over the top and just get the cats and headers off him.

He said that he's had a problem with this seller, ends up that they're cheap copies.


regarding the online performance we have come across it where they sold a
system to a guy and he brought it here for fitting and it was a cheap import
system so be careful .

[Wonky]

As Wikky said, exhausts are very subjective. I had a full 3" KPM system on my SSV sedan and it was so awesome that it was the first thing I ordered for my SSV ute. Most people who heard it said it was the best sounding bolt-on VE they'd heard. When JKGMH heard it last week he wondered whether it had a cam due to the powerful throbbing at idle.

One day at Chev's when the KPM system was due to go on the ute there was a DF 3" VE system someone had ordered from Darren and my KPM system on the floor next to each other. There was absolutely no comparison in quality!! The DF system looked like a piece of cheap crap compared to the KPM and everyone who was there that day agreed (can only remember that SenatorMike was one as it was the day he had the 3" HM system fitted to his Senator).

http://i122.photobucket.com/albums/o274/gcovo/SSV%20Ute/Exhaust/KPMute1.jpg

[VXSS346]

Wonky's car does sound awesome too. Probably the best VE system I've heard too.

As for DF quality, I was there too and saw the two systems together, and yes it didn't look as good, I wouldn't say it looked like cheap crap though. :) In any case, should it be about the looks? It goes under the car after all.
They are still top quality systems.

Cheers :)

[GRUNTS]

i've just had a full di-filippo system fitted to my blown 408, 1 7/8'' extractors and complete dual 3'' and i could not be happier with it, tucks up nice and neat so no scrubbing issues, sounds orsome not to loud nice deep note and no drone what so ever:goodjob:

http://i122.photobucket.com/albums/o274/gcovo/SSV%20Ute/Exhaust/KPMute1.jpg

And the price of this system is even dearer again at $4600 + delivery + fitting!! These prices are just crazy for an exhaust. I know that everyone says the VE had drone issues and it took abit of figuring out, so now we pay twice as much because manufacturors took 10 min to scratch there heads and work it out. A little price rise is fair enough but i can't get my head around $5000 for some of these exhausts but while ever we pay it they'll sell them.

[SS Enforcer]

The price of the VE systems is a bit over the top but heres a suggestion... just put a cam in it and any system will sound good :)

As for the Di Filippo gear I have seen a few and think some of them look ok but the headers look a bit suss around the collector but certainly sound sweet. I will probably set a set for mine if i come across a decent 2nd hand set.

cheers

[medz]

I've got the diffilipo 3 inch on my ve ute. The sound is perfect could be a little bit louder but not to much. Definately a bit pricey, but that's what you get when you want quality I suppose.

I origanally wanted the KPM system but they wouldn't take off the fitting charge even though they wouldn't be fitting it, Which is a shame I was really keen on it.

[BEARWOOD]

Why would they charge for fitting if they wern't doing it? I look like putting a cam in and might leave the standard exhaust on to start with and see how i go.

[matygeenz]

so how much is the kpm system 3" catback and how much is di fillipo system.
Does anyone know if either of these system would bolt up to xforce cats/headers........

[medz]

Why would they charge for fitting if they wern't doing it? I look like putting a cam in and might leave the standard exhaust on to start with and see how i go.

I'm from W.A. So the system needed to be mailed here obviously. The price on there site is the fitted price. For some reason the guy that I spoke to wouldn't take the fitting charge of that price even though it was getting mailed to W.A. He said it was more of a reward/incentive whatever you like to call it for Adelaide people to come in.

Shame cause I would of bought it if they had. I got my difillipo system for $4100 to my door and fitted it myself. That's extractors Cats and Catback

[GMMAD]

thats VT-VZ not VE

[Podge]

$4100 was just too pricey for me... im considering one of the Mr Mufler F1 systems

[Wonky]

I origanally wanted the KPM system but they wouldn't take off the fitting charge even though they wouldn't be fitting it, Which is a shame I was really keen on it.

Interesting! I hadn't realised that the prices quoted on their website included local fitting. One extra the KPM system has over the DFs I believe (and may be wrong) is the KPM includes ceramic coated extractors, which is about $300.

Maybe it's due to the economic downturn but I know someone who a few months ago bought the full KPM 3" system for the same prices being quoted here for the DF system.

[BEARWOOD]

Youd think they would take the fitting charge off knowing that it was going to another state and there was no chance of you going just up the road to the copetition and getting it done. Anyway they lost out of not only selling another exhaust but some free advertising that could of led to a few more being sold.

Wonky, was that new and from KPM themselves at that price?

[Juchno]

I paid $4100 fitted, full system.
The sound is loud but very, very clean.
Sounds amazing on idle and up to 3000rpm, with a very defiant note that lets everyone know that its a V8.
Anything above that and your roaring.
You could probally compare it to that Db of a lambo opening up.
Different sound but clean and loud.

I thinks tha MAFfless air intake helps to that note aswell.
I get all my works done at C&A Auto Fashion.
They are really good on price but also only use the best gear.

The expected output after the cam and diff is in the range of 328-340rwkw.
Hopefully i get at lease 328kw and il be happy.

If someone could tell me how to put picks up i will, not sure how though.

That price is for the 1 3/4" headers i take it? are they hpc'd? its a good price for a full d/f system cause according to darren they're normally $4500 for that system.

[BEARWOOD]

You must be putting a pretty big cam in it if you expect those numbers...

[Juchno]

Yer its is 1 3/4".
The boys down the shop look after ya pretty well if ya get a bit of stuff done.
I think being that they would be a few they would probally get great prices to.
Thanks

That's how I always used to explain it too but for a month or so the little yellow "Copied" box has stopped appearing and I have to specifically right click and copy. Have had a quick look but can't see why it changed. :(

Good to see another man with pristine taste!! :D White SSV, lowered with flat hardlid. Was the hardlid from Trev in Dandenong too? My parents live in Croydon so if ever you see mine stop and say hello! :)

That kpm system sure looks top quailty best workmanship think ive seen on the forum bought back some memories my old remus race a few years back apart from completely blown baffles in the rear muffler and making the car sound like ping bong wheels when i revved it also had rubber bands holding the rear muffler exhaust section to the bracket at rear of the car, i did a touch up job on route to the exhaust shop it was virtually falling off the car the bloke installing the new system nearly fell over backwards when he saw it , the previous owner welded or sorts of weird pipes big and small

[Juchno]

Na it came from Bluey's ute world in bayswater.
I would agree though, Dont like the raised lids, they look to jap. Which i think the Maloo's rear window trimps make it look aswell.


Very nice ride though (yours)and wheels i might add.

Nice exhaust, but like what was said before.
Its under the car, so the extra cost is for the look when its not getting looked at.
Each to his own though

Carnt say iv heard one, love to though.
Have you had anything else done?
and whats your rwkw?

[STATIE]

Gee - that picture's real purdy but I don't really want to climb under my cars & flog off on some shiny mufflers.

I put Difilipo's on all my cars because they sound the best & go real fast.

Looks good up on the hoist! :lol: I think as I said earlier that a lot of the difference in cost is due to the KPM system having ceramic coated extractors.

At the moment the ute has DUS OTR, mafless tune and 3.45 diff (originally 2.92 in A6). For a bolt-on A6 both it (L76) and my previous SSV A6 sedan made the best numbers of any L76/L98 A6 on Chev's dyno, into the 260s, so the KPM system flows very well. The ute figure was at only 1,800km with original diff.

Have yet to do a fly-by video for the ute but do have one from the sedan.

YouTube - Wonky's KPM System (Short) (http://www.youtube.com/watch?v=89Y2yWve8QE)

[Juchno]

Does sound quite nice.
But im a bit prone to Di Filipo, probally cause thats what i have.
Question? Why the Auto's?

[LBY00T]

Juchno - Any chance of getting up a sound file for us all? :D

Would love to hear it idle and under a bit of load ;)

Hi there Wonky, From a man who has owned both the sedan and the ute is there any differance in the exhaust sound between the two?...I was told that the exhaust is turned differently to accomodate the ute back...which results in a nicer note. any truth to that?

[Wonky]

Question? Why the Auto's?

Fair enough - I'm the same. If you're happy with what you know and love why change?

Much as I'd love a manual (the rest of the family inc wife and 2 daughters, one with a VY2 SS) all hate autos but it's all I can drive now due to disability. No need to apologise if you feel embarrassed or something now as others have done in the past as you weren't to know and I don't hide it (impossible now anyway :lol:). Bit of a comedown for someone who used to have a heavy truck/bus licence. :D

Are you talking specifically KPM systems or in general?

The sedan had the full standard KPM 3" system inc 1 3/4" Pacies and their own Mega cats which I believe are 150cpsi. On the ute I have 1 7/8" Pacies and the 100cpsi Ballistic cats, each of which I thought would have made it louder and deeper. On first start up most people thought it was neither as loud or deep but now as it's carboned up it's probably about the same as the sedan was i.e. it didn't end up deeper or louder but about the same. I must do a fly-by video soon but I expect it to sound the same.

[Oompa]

Juchno,

Any chance of recording the sound and posting it?

[Juchno]

I'll try and get a sound file in the next few days.
Not really sure how to go about it all but I'll get my mate to works out the finer details.

Nah, as I said, no need to apologise. The wife and kids all have manuals and hate autos - wish I could join them. :)

[DCV1NU]

Had my Difilippo system fitted a couple of days ago, so far im loving it especially on first start ups sounds f**in horn!

Here's a quick vid, not the best but you get the idea.

[jai]

Im just gunna throw up my 2c and say that my Xforce is way waaaay better.

I got the 1-3/4" headers, cats & 3" catback for $2300 in Stainless. Fitting was $300. So for 2600 im done. And the fact is the car is as good as stock cruising around sound wise, zero drone and then WOT I cant hear bugger all anyways...

So you pay $2k for a sound you dont get to fully appreciate anyways? :)

JK

[255-LS1]

Personal pref but the difilippo's sound alot better in person compared to the xforce, only reason why i went with Difilippo was because i didnt like how loud the xforce system was & it kinda had a diff note to it(not a a good way). I was looking at getting the new pacemarker system which is $3600 using their euro 3 cats but that price was for a twin 2 1/2inch system:confused:

[ebbett21]

Agree totally i personally think DF sounds deeper/refined however each to there own sound

[shiny_suit_man]

Just want to tell everyone that Di Filippo make the best exhausts around.
Got on on my Ve ssv, a 3"a.
Best sounding exhaust system ever.
No Drone just pure 6.0L of sound

Thanks to this and, MAFless air and a retune I now have 280rwkw.
Loveing life.
Not quite enough power though, so its booked in for a 3:7's and a cam.
Should be quite nice.

So if you have the $$$$ Di Filippo all the way.

No XForce

How did you go in regard to heat sheilding with them mate? A bloke i work with had one put on his maloo and they put NO sheilding on at all, melted his steering column and wiring looom.... So i wont be going down that path after hearing that...

[GTS307]

i rang darren friday i think his prices are $4100 for a full system with duel 3" $2200 for a 3" cat back and $1800 for a 2 1/2 cat back in stainless i think there is somewhere in melbourne doing better prices on his systems

If anyone is interested i have the 2 1/2" stainless steel cat-back which is brand new never been fitted for $1300

[stringer1050]

some thoughts on this would be good, VZ Maloo with full 3" difilippo exhaust center and rear mufflers... not quite loud enough for my likings, would you remove rear muffler completely or replace with hotdogs?

Cheers

[vz300]

These exhausts are over priced hype, looking at the first page who on earth would pay $4100 for a system unfitted, guess thats how a top fuel car is funded......


Be great to put a few systems side by side mix up the names and see who picks what...... Cant help but think the sound so great because Di Filippo has his name on it...... Just my 2c

[VYClubby]

These exhausts are over priced hype, looking at the first page who on earth would pay $4100 for a system unfitted, guess thats how a top fuel car is funded......




I agree. A DiFillipo system may sound slightly better depending on who is listening. But performance wise dual 2.5 inch pipe is dual 2.5 inch pipe. I doubt there would be any gain in power with DiFillipo v XForce, so it's not worth the extra money.

I reckon my XForce sounds o.k?

Ive just sold my xforce 3'' and put a twin 3'' mild steel rage system (NZ) and have to say the car feels 10 times stronger down low and mid range im thinking the X Pipe on the xforce is smaller than it should be. However id love to try a twin 3'' Diffilipo in comparison to the one now

[VYClubby]

the car feels 10 times stronger down low and mid range

Wow! 10 times stronger who needs a cam! :rofl:

hmmm yes cos we all put exhausts on for just one and only power increase. Ask anyone who fits an exhaust 9 times out of 10 it will be cos they want a decent sound. 2.5 inch pipe is 2.5 inch yes, but mufflers are not equal, nor is the material type thickness used for the muffler construction and tubes etc. DF custom makes his mufflers, does xforce do that :confused:

My twin 2.5" xforce cat back has shit itself, welds broken mufflers fallen apart inside. Sure its sounds "ok" but for the reason of it dying i wont be getting another xforce, id rather spend the extra coin on a DF and know that its the best sounding system and it will last.

My 2 cents. Enjoy your xforce.

[MrSuave]

I have just ordered a DF exhaust for my Addy based on
1. Sonny @ Merrano's recommendation
2. The quality of the materials used
3. After speaking to Darren himself, its obvious that he knows his stuff and would never produce crap.

I now know that it will sound as good (if not better) than other systems (in my opinion) around and flow really well. Also the peace of mind that the product is backed by both the supplier and manufacturer if there was to be an issue of any sort (which I doubt)

[gavlotic]

don't know if anyone has noticed. But i was flipping through street machine magazine over the w/e and noticed DF's new add looks like there's a upgraded version of difillipo headers available now for vt-vz. Still long tube 4 into 1 but has a more professional looking merge collector rrp around $1400 though. anyone try these yet?
plus there are merge collectors available for $300 each i think it was.

cheers.

kk, Never put an exhaust on a car before this one,
bought a 2.5" system for a 03 monaro from di filippo. Stainless from extractors to tips with high flo cats.

self fitted, and this may explain some of the issues I will now put forward.
I get drone, its not bad, but its there, from like 1200 - 1400 rpm, around town speeds, does not appear to be audible outside the car though, and this seems odd to me, also when the car is cold you can hear a rattle, from the same spot as the drone, I am assuming that I have stuffed something up when I put it on, but still.

Also seemed to lose some guts down low, however once you give it a kick, its a different car, took a bit of getting used to.

The workmanship on the pipes was better than good, some of the welds on the headers looked like the ones out of my textbook, whereas some of the ones on the cats were pretty average.

As I have said, Never had an exhaust on a car before, and I have no real basis for comparison, but I think its a good system, and in regards to price, how many exhausts are you REALLY going to buy? Go ahead, spoil yourself!

[Sonnymad]

Gee - that picture's real purdy but I don't really want to climb under my cars & flog off on some shiny mufflers.

I put Difilipo's on all my cars because they sound the best & go real fast.

Now that is the best statement here !! statie has actually run very fast using di fillipo systems,just cause the mufflers are shiny and there made in china and cost the seller bugger all ,making a 500% profit margin,dont let a few shiny mufflers fool you guys,pipes are pipes whether their made by di fillipo /x force/etc....and again,straight thru mufflers are straight thru,doesnt matter who makes them,the key is in the headers....and another note,buying products made here in australia supports australia and australians jobs,the way thingss are going,soon there wont bee any jobs in australia as the mosst manufactrers are packing up and going to china !

We cant compete when it comes to manufacturing in Oz, labour cost is too high.

As a consumer, why should I pay more for a product thats made locally when I can buy an import which is as good, if not better, at a cheaper price?

It would be better for him obviously, most businesses are, most of the parts made on a VE are from China, Thailand or Indonesia Im guessing. No WorkCover or OHS laws to worry about there.

Workers rights, everyone knows they dont exist in this day and age, why do so many folks set up their own biz? You and myself and many others included.

Im becoming a grumpy old man :lol:

drone at that RPM = who drives at that rpm labouring, change gears mate :goodjob:

lost guts down low = have you had a tune to compliment the new system, if not get one.

DF are the best sounding and quality system, anyone who doesn't admit this is either having a laugh or too tight to fork out for a top of the line aussie system, not some china crap.

statie pretty much sumed it up

cheers

[ebbett21]

DF are great sound but expensive, whereas xforce half the price, thats why they are popular

[ebbett21]

Wow! 10 times stronger who needs a cam! :rofl:

yea xforce chinese crap with a chinese bling bling note to match haha

[knockout]

Sonny@marranos recently put on a dual 3" DF with headers to match on my VE, must say i am very happy with its nice deep V8 sound.

My decision was made when his off sider Murat took me for a drive in an xfoce dual 2.5". Sounded ok, but was very tinny and not a real deep noise. They guaranteed the DF would be better note and quality, so i put my trust in them. And as stated i could not be happier with the DF:goodjob:

[Toast]

I'm thinking of changing my cat back to either a DiFilippo or X-Force Maloo style system in the next few weeks.
What's the difference in noise level (db) between a 2.5" DF system and a 2.5" X-Force system?
I like my cars loud, round the 98 - 100db noise level (sort of wake up the neighbours loudness :lol:) but I hate drone!

My VZ SS 5.7 Ute currantly has Sureflo 1 and 3/4 short 4>1's and 4" Ballistic Racing Cats.

[Evman]

X-Force is louder, which I no longer like. Cops are getting too strict these days :( Even my DF is a bit loud IMO :lol: It has such a deep note though, I love it

good post mate, from someone in the business

[blackbettyhsv]

hope this does'nt stir up the pot too much, but Im thinking of selling my 2 1/2 inch difillipo system for a 3 inch kpm system.
mainly as Im thinking of a cam later & I have been told the 2 1/2 inch wont be sufficiant enough, I also heard (wonkys) SS sedan a few years back & as much as I like my sound his set up was a deeper louder sound.
the only prob I want to keep my standard headers as I cant justify the price of them for not much more Kwatt gain, & kpm dont make a system to match up but will sell me the cats & get someone local to marry everything up to the headers, which can be done.
I just dont know what my system would be worth to sell

[BEARWOOD]

I sold my dual 2.5" Difillipo catback for $300 about 2 years ago after putting in a cam and went a dual 3" from CHE and picked up around 5 rwkw with a touch up to the tune. I had Difillipo headers an cats aswell but and kept them on. I don't think there would be a restriction in the 2.5" catback after putting in a cam, i think it would be in the standard headers more so.

[macca33]

Blackbetty, plenty of VEs running around with cams and twin 2.5" cat-backs and making good power. You would be better served by putting some decent extractors on, otherwise you won't be gaining anywhere near the full potential of the cam.

KPM cat-back (which, by the way is a great system) = a whole lot more $$$ than extractors and 3" metal substrate cats.

cheers

macca interesting you are the first person to say that, most are saying to change to 3 inch & cats & leave the headers.
me not being into this side of it, makes it hard to decide, I did speak to david at KPM he reckons to keep my headers & change the rest, maybe I will speak to a bunch more people as to what to do, but yeh if I only change my headers & cats that would be financially better towards the cam

[macca33]

Whilst I won't disagree with David, he may have other considerations, with regards to exhaust inquiries.

Exhaust gases are at their hottest, thus consume more volume, as they exit the engine and enter the exhaust. They cool and contract, as they near the end of the exhaust system.

The capacity for greater flow, ie larger pipes, where the exhaust gases are their hottest, makes plenty of sense to me.

cheers

To be blunt, he is trying to sell an exhaust to you at which he will make money off. They are a business and thats what they do. They sell Pacemaker headers with there systems and do mark them up quite a bit but the money would be in there system's that they make themselves. Like i said above i gained pretty much nothing by changing to ma 3". Do your headers an cats.

ok say I keep my exhaust,(not knowing it will be ok) which type of header & cats would be best suited then

[Lincoln87]

1 3/4 - 1 7/8 long 4into1s.


correct me if im wrong.


all brands will do basically the same thing, what brand you go with will depend on your budget..

[blackbettyhsv]

its not the budget its the best result at the end.
which is why I ask questions on here so I hopefully get the best result

[BEARWOOD]

There is heaps of different brands of extractors and i doubt you would feel the difference between any of the well known 4into1's so just pick a set that are reasonably priced and made. Difillipo are prob towards the top of the price list then there are Pacemaker, Hurricane etc. that seem to do the same job for less $$$.

[slr490]

yes they are a great exhaust

[fireguard]

Has anyone here purchased an exhaust through ebay? They have them at a good price from exhaustshop but i'm a bit hesitant buying it online. Anyone know whether it's worthwhile or not?

[255-LS1]

yep i bought some HPC coated DF headers from exhaust shop. no problems.

[fireguard]

Awesome, cheers mate. Fingers crossed i can get some cash and get one soon!

[BECAUZ]

Ok didnt want to open a new thread so hopefully my questions will be answered by the V8 lords

I've finally decided and made up my mind about which exhaust system to go. Im going to get difillipo headers and difillipo exhaust 2.5 inch.

Every morning before i go to work i turn my car on in the driveway and warm it up for 5 to 10 mins before i head off on my way. Will the exhaust be so loud as to annoy neighbours? Or would it be acceptable. Currently the car only has a otr and mafless tune.

How loud would it be at idle in dB? (approx)

Will i also need a stereo upgrade to hear the tunes?

How loud would it be in the cabin? I sometimes have clients in the car and dont really want them thinking im a hoon, not that i really care but would kind of just like a heads up.

Last of all if i was to get pulled into the pits would it pass epa?

Never had a V8 before especially not one with a $4500 exhaust set up. Oh and Its just about set in concrete coz i've already booked it!

[255-LS1]

off topic make sure you get tips fitted when the exhaust goes on cos the std DF tip pipes on the twin 2.5 VE models look :limpy:

[moby]

hi guys,

im picking up my ve ssv in a couple of months and i need some exhaust advice. I definately want a difilipo setup.

1) I've heard the std cat back is pretty efficient - i.e. if i put a good set of headers on it it will produce the same power as someone with a full difillipo setup - is that true? Does anyone run this setup - I'm assuming it will also raise the sound level a bit?
2) If i go the full difilipo setup i'd have to go the 2.5" as the cops are bad in the small town that I'm from.. what size difillipo headers should i get if im planning to install a baby cam in the future?

cheers,

Warm up for 5 minutes? You do realise cars dont actually need warming up right? If you got a decent exhaust your neighbours would get pretty sick of you pretty quickly... the drone of an exhaust can carry quite easily and quite often will be fairly boomy to someone over the road or next door. Even worse if you have a roller door and its down.

I would hardly think your car needs to be idling for an extra 50 minutes a week mate, it does nothing for engine longevity!

But is it not better to have your engine warm up under no load then to warm up under load? Thats what my understandings always been.... Could be wrong.

[jai]

But is it not better to have your engine warm up under no load then to warm up under load? Thats what my understandings always been.... Could be wrong.

There is a difference between driving to work at 7000rpm every gear change and changing gears at 3000rpm or less for the first 5 minutes. The subtle difference is being a toolbag or not :) Chev V8s warm up fairly quickly... and besides, your engine might be warm but the rest of your drivetrain aint.

The warm up theory is nearly as good as the warm down theory for turbo cars... its all about how you drive toward the beginning or end of your journey that makes all the difference.

[BECAUZ]

cheers jai. thought i'd open a thread about other thoughts.

[HQLS1]

I agree, Difilippo have the best sounding systems on the market and the quality is second to none. As stated numerous time on here its a case of you get what you pay for. If you want the best and can afford it Difilippo are th way to go.

[ypad1]

Interesting thread....Am going to be in the market for an exhaust in the near future (next 2 weeks or so). Been reading quite a bit and at the moment it seems that x-force is not as good as it used to be a few years ago. One of the main giveaways is the price...I've been down that road of cheaper stuffs before, etc and unfortunately most of the time you get what you pay for.
KPM sounds interesting but I have to check about this fitting charge that some people have paid even if they are not getting it fitted. It might just be token amount of $$ but I don't like that principle.

[V28VX37]

I've finally decided and made up my mind about which exhaust system to go. Im going to get difillipo headers and difillipo exhaust 2.5 inch.


Top choice mate, I've got the same system on the Monaro (4-into-1 1.75" headers and dual 2.5" pipes) and it still sounds unreal after all these years. Looking at the price I trust that you're getting high flow cats as well?

I had a Remus catback before and the DF is on a whole different level.

It's definitely not a quiet system though, especially when teamed up with a H/C package. Still, never had any trouble anywhere (knock on wood); that said the car is a weekender.

Highly recommended!

I've got the dual 3inch system with the 1 3/4inch headers on my ve, before i had the tune done it was VERY loud on a cold start(enspecially during the colder months) but after the tune it quitened down abit & the note went alot deeper. Cabin wise the system isnt noticable unless you've got your window's down & even then its not very loud.

[KrisR]

I've got a full DF 3" system on my CV8Z and couldn't be happier with it.

Externally the exhaust is not that loud at idle, has a very deep V8 rumble, when you open it up you can tell it's there! :D

From the inside of the car you can barely hear the exhaust! You need to close the windows & mute the stereo and even then you hear a faint sound of it and that's with 3.9 gears.

I also purposely had the stock CV8Z tips put back on so it basically looks 100% factory, should the fuzz ever want to take a peek at the car.

Kris

[BECAUZ]

Sounds good cant wait!
Just installed a countdown clock, 28 days 16 hours 25 mins and 55 seconds before installing the new exhaust begins!

[Wonky]

But is it not better to have your engine warm up under no load then to warm up under load? Thats what my understandings always been.... Could be wrong.

On motors many years ago that was the theory. On modern motors just drive them easily (no WOT or high revs) till they're warm. My SSV has an oil temp gauge and I'm surprised at how long it takes for the oil to get hot - depending on the day etc can take at least 10kms (country traffic) or more.

[Wonky]

I agree, Difilippo have the best sounding systems on the market and the quality is second to none. As stated numerous time on here its a case of you get what you pay for. If you want the best and can afford it Difilippo are th way to go.

Disagree in a way - look at a DF and KPM side by side as we did at Chev's with my KPM and a DF system someone ordered and there is no comparison in quality - the KPM looks infinitely better!! Not only that, the KPM 3" is the best sounding VE system I and many others have heard and has the results on the board for power. My A6 bolt-on ute did a low 12.8 at the LSX_Shootout and Black Diamond's cammed A6 did an 11.7. Plus the KPM systems are now slightly cheaper than DFs and include ceramic coated headers.

[Wonky]

KPM sounds interesting but I have to check about this fitting charge that some people have paid even if they are not getting it fitted. It might just be token amount of $$ but I don't like that principle.

Never heard of that before!! I've bought 2 KPM systems and know of others who have and we've only ever paid freight from Adelaide (around $100 from memory - quite reasonable given the size/weight of a full system).

[duke5700]

Well I stood behind Wonks ute the other night and I am a big Di Fillipo man but that KPM Exhaust is horn.

Thats defantley not true !!!! think of it this way,if a engine produces more power,it produces more exhaust gas :),that gas must leave the engine quickly as possible !!! it aint gonna happen with the std headers and cats !

I agree Wonk's having been for a ride in bd's black bleast! As much i as i love the sound of the df system, i'd get a kpm system the second time round as the sound is horn especially when cammed & there's a shit load more ground clearance than the df system.

[monta7]

Just want to tell everyone that Di Filippo make the best exhausts around.
Got on on my Ve ssv, a 3"a.
Best sounding exhaust system ever.
No Drone just pure 6.0L of sound

Thanks to this and, MAFless air and a retune I now have 280rwkw.
Loveing life.
Not quite enough power though, so its booked in for a 3:7's and a cam.
Should be quite nice.

So if you have the $$$$ Di Filippo all the way.

No XForce

hey mate i have a 6.0L an i had 1 7/8 di fillipos 3 inch cats an 3 inch di fillipo catback sounded amazing if you have the money its the way to go

[Vt_vic]

dunno about ve but i got quoted 995 for difi headers and 800 for cats all 3" and 600 for a twin 2.5 catback for a ls1 i dont think thats too bad but as i said i dunno about the ve

The headers are bout the same price but the cats are $350 each, the cat back is $2100 for ve...all up i paid roughly $4k inc fitting & 4 stainless tips.

[brentonsav]

in this month's motor mag, gmm have a special on for ramjet otr, di filippo 4 into 1 long tube headers, hi flow cats and ss catback with tune
in 2.5 or 3in - $4690.

pretty good compared to some of the prices around the traps.

[j0k0]

not a bad price, wouldn't mind going in there and seeing if they would replaces the DF for a KPM and dropping the price a little more :)

[QldKev]

Also shop around. I know it's not a di filippo, but I recently got
XForce 4into1 Extractors, High Flow Cats and 2.5inch cat back, inc fitting + DUS OTRCAI + mailorder tune for $2,840.

I know the XForce cats havn't had a good run; but I beleive they have sorted the issue. And I love the sound of the XForce system.

You'll be pretty happy with that combo, the 3" is too loud (and clearance is an issue).

I've had the xforce cats on for maybe around a year or so, not had a problem until I got stuck on a driveway and almost tore the catback off, replaced the gaskets and it's as good as before.

Good to know. I have a Sureflo 3.5" catback at the moment and am looking to add headers and cats - I was going to use the long DFs, but will now look into KPM.

Can anybody who has the long DFs and low King Springs up front advise clearance from the flange to the ground. Also, will both KPMs and DFs clear the Calais power-steering rack?

[QldKev]

You'll be pretty happy with that combo, the 3" is too loud (and clearance is an issue).

I've had the xforce cats on for maybe around a year or so, not had a problem until I got stuck on a driveway and almost tore the catback off, replaced the gaskets and it's as good as before.

When I first got it I though it was too quite; it has now got some carbon in it. Now I love it; you can sneak out of the street early mornings / late afternoons, and when you get on the gas it lets you know it. I paid $1740 for it fitted and value for money I think it rocks. I'm glad I didn't go for the 3inch or the loud 2.5inch.

The di fillipo and KPM may be better exhausts :goodjob: ; but I wouldn't have it yet. To me I'm better of putting the extra money into the CAI and tune (as I have done) and eventually a diff and stally.

[Wonky]

Also, will both KPMs and DFs clear the Calais power-steering rack?

Can't answer that directly but KPM use Pacemaker headers (ceramic coated). Their systems are well tucked up - even with SSSL springs are round on the ute I rarely scrape, although do take bigger speed humps very slowly. :)

G'day guys,

my s2 ssv ute just arrived and I'm keen to get some parts installed before I bring it up to Sydney. From what I've read diflippo is the way to go despite being pricey - only thing is I've never heard the exhaust note in person. Would anyone in Sydney With a ve ss 2.5 inch difilippo setup (headers and cat back) be willing to show me how it sounds? I live just just over the bridge and I'm happy to travel say half an hour. Cheers

We have plenty of di fillipo setups,give us a call we can organise a car for you to have a listen to

thanks sonny ill give you a buzz hopefully i can see somethign this w/e

[etrocket]

personally I cant justify spending 4k on steel but what ever floats your boat. im sure other cheaper brands do the same job for half the cost.

what people are prepared to pay = brand

[Evman]

If all you want is a few tubes that get the exhaust gases from the front of the car to the back then yes, any cheap exhaust will do it. If you want to be sure the welds, mufflers and even the steel itself will last more than a few years, and be guaranteed there'll be no drone whatsoever while offering a range of sound levels rather than just "bullshit loud" then you have to be prepared to pay extra.

So what are u saying that anything other than DF is no good. As with most of the 1000s of people viewing this forum there is no conclusive proof that DF is better in any respect. Sure people can have a liking to a certain noise that different systems make....good buy the system then. I have heard over 10 different set ups and they all sound great but, as like everyone else, I like certain ones. All headers/ cats and systems sold by the main players have all had their R & D done on them and they all have proven that they enhance the vehicle's power and torque. So if you want a Dyno Queen get an exhaust for that to enhance your setup, If you want a torquey street racer get one that enhances that set up. From what I have seen all companies mentioned on this forum have top notch products, good welds, pipes, good range of options....so price is just a result of what u want and what you can afford.....2 kWs here 10Nms there...who cares. My point being you can't lose. Any decent headers and exhaust with a tune will give u good power and torque increases and the right noise you like.....for what is worth i love the noise of the 2.5 inch tri-y set up....slightly higher pitch and the spitting and crackling on 'throttle off' is awesome.

[255-LS1]

this is funny. i bet there is no one that has had a DF exhaust before that would dare put anything lower in quality or sound on their ride. Once you've tasted and heard a top dollar system you simply cant go back no matter the $$$

[Evman]

vitob I never said anything about DF exclusivity, I was talking about paying extra for a high quality system over a cheap system. There is a huge difference in the sound created by different catbacks, and a huge difference in manufacturers interpretation of "no drone". Extra money will get you quality metal, mufflers, sound and (usually) build quality. Saying "I love the noise of the 2.5" tri-y set up" doesn't mean much because there can be a massive difference between systems of the same size.

[jaykay]

Car colour I mean :rofl:

[conrodss]

I am about to drop huge coin on a Difilippo system , In the end it came down to 4 systems as I could only find 4 that will NOT drone, and this is main point as power can be made with just about all systems.

1. KPM looks good and should be good , but to sydney was quoted $4050 then would have to be fitted. extra for hpc

2. VCM , don't like how CATS are welded to headers , still to Sydney $3900 plus fitting. extra for hpc

3. Surfeflo , great system . but quoted $4350 fitted. extra for hpc

4. Difilippo , tuner stands by it 100% although he said can achieve similar results with any of the above. $4100 fitted. extra for hpc

So for me the difilippo system is the winner just on cost . strange I know.


now for the rest , xforce , look great , but terrible DRONE , any other generic system. DRONE , any exhaust shop can fit an exhaust and it will take gas from engine out the back ,

but I just dropped 40K on a car , why fit substandard stuff to save what maybe $1000 .

[-shady-]

this is funny. i bet there is no one that has had a DF exhaust before that would dare put anything lower in quality or sound on their ride. Once you've tasted and heard a top dollar system you simply cant go back no matter the $$$

i had a full df system on a previous 5.7 it didnt have a rear reso so was a bit loud and raspy but sounded ok, got the 6.0 and changed to stainless x force extractors, 100cpsi ballistic cats and 2.5 cat back that was already on the car when i brought it
no drone, saved heaps and sounds awsome couldnt be happier

so how much was the bet for?:)

[Wonky]

Agree 100%!! :yup: The guy who bought my SSV sedan talked me into selling it with the KPM system still on it for extra $ because he loved it so much (as my ad said, I was going to take it off to transfer to the ute and put an XForce on to sell it on with). With the cost of the ute and hardlid with actuators etc I found myself in the position where I may have had to instead go for a cheaper system and after the beautiful sound of the KPM that concerned me greatly.

However, I made some sacrifices elsewhere and got the KPM again - absolutely awesome, especially now with the (small) cam. A short clip from the cruise (window was down).

funny you say this ev. i recently had to repair some welds that had cracked on one of these higher end exhaust. the catback wouldnt even be 1yr old yet and had quite a few decent sized cracks in the welds.

[Wonky]

1. KPM looks good and should be good , but to sydney was quoted $4050 then would have to be fitted. extra for hpc.

Unless you were being quoted almost $400 for freight :weirdo: then at $4050 or so the headers would have been HPC. See http://www.kpmauto.com/tabid/379/Default.aspx Allow $200 or so for fitting and you have an awesome sounding system with HPC for not much more than the cost of the DFs.

I know someone on here who a few weeks ago went from a full DF 3" on his SSV to a full KPM 3" and is absolutely rapt with the KPM! :yahoo: DF VE headers are very low and he got sick of scraping them plus when he went from stock 2.92 diff to 3.27 he started to get some drone. No drone at all with the KPM.

[jaykay]

I'm waiting for a Di Fillipo and Manta prices now, but I have had 6 different combinations priced for my Senator and the fitted prices in Perth are between $2900 and $4400, depending on HPC coating and mild steel vs stainless catbacks.

The dearest so far is the KPM system :bawl:

[sjhugh]

DF VE headers are very low and he got sick of scraping them

Wonky, you ain’t whistling Dixi. I had DF on my VE Ute and the Header/Cat clearance is the real downfall of the system. On a lowered car it is sh!tfull. I won’t be going in that direction again.

[Evman]

Everyone has bad batches :yup: Some more than others :stick:

[vitob2006]

Totally agree. That is my point. If you did a blind study where no one knew what exhaust was on a car and 10 of the popular exhaust companies supplied their products, then they were installed dynoed, street tested, drag strip tested, 10 000 people gave their opinions on noise and driving characteristics of the cars, their would be no clear winner. How many times have you heard people saying on this forum that they got told their exhaust is awesome......funny thing is its not exclusive to any one exhaust manufacturer. Also the drone comment is very subjective....I used to to have a valiant with headers 2.5 inch running into 3.5 inch....droned like a #%^&%.....loved it and the note at idol was booming you would feel it vibrating on your heart...ha ha...people would say 'Man tough exhaust'.....I suppose if I had a DF or Sureflo or Mantra or pacemaker or Xforce or GreatWallMotors exhaust sticker on the car people would wanting one regardless of price..btw if you dont want drone put a resonator in somewhere.. Again my point being all the top manufacturers have got top products or they wouldn't be in business and its personal preference(noise) and whats best for what the performance objective the person has for their car...cheers

[KrisR]

I'd quite happily back Sonny up on the comment of Di Filippo systems and ground clearance as he fit mine to my CV8Z and is quite low (Pedders XA's). It's the DF 3" dual full system and has never scrubbed anywhere other than going over one of them sharp $hitty Bunnings speed bumps too quick - and I have the tinest of scratches on the cats to prove, not massive scrapes or gouges. Other than that, the note of the DF system is sensational. All of my mates have heard my car has commented on the note but coupled with a mild cam now it really does turn heads :D

Kris

PS. Sonny never got a chance to thank you for the adjustments to my tune that you made a few weeks back!

I had the D/F 1.75" 4-1s and twin 3" cat-back on the last Senator. It sounded great - no drone - and well and truly let the ponies run wild.

Sure, there are other manufacturers and imported bands out there, but D/F is good enough for me. The same gear is going onto my new rig.

sorry guys but I have a full ceramic coated headers 3 inch stainless KPM system & although it sounds great the bloody thing scrapes on speed humps & anything else that sticks up.

When I had the Pacemaker 1 3/4" headers on my SSV with Manta cats, the cats used to scrape a lot and my car wasn't radically lowered.

I'm wondering if the Di Fillipo headers finish in a slightly different place to the Pacemakers ?? :idea:

That would be a very Bad move in relation to scraping I know of a few people who have changed from the DF headers & cats on VE's that are lowered due to very bad scraping issues.

My Senator Sig is lowered with Walkinshaw MRC springs I have no scraping issues with My KPM system. Pacie 1 7/8 HPC coated headers, ballistic cats & 3inch KPM. & previous system I had on it was a full HM Perry no scraping with that either.

Im lucky in that I dont drive mine much so maybe I should put up with it, the system is a great sound that is why I got it, only prob the cats are only 60mm from the road, the other thing I could do is chuck a set of 20's or 22's on it

[DCV1NU]

Guess i should throw my 2c in...

Speaking from personal experience having switched from a full 3inch DF system to KPM, both systems are good quality well made systems but the issue that i had with my DF system was that the cats hung very low where as the rest of the system sat up high the fact that i started to get droning when i upgraded my diff gears.

Now my car at that point my car was lowered but it wasnt stupid low, i found that going over 90% of speed bumps with just me in the car there was no issue but the minute i had someone else in the car i had zero chance of clearing it. I ended up taking the car to Darren himself twice to see what he could do to tuck up the cats higher, but both times in all honesty he did sfa which really pissed me off.

When i recently upgarded my diff gears i noticed straight away that the system started to drone, i didnt think too much of it at the time but it did get worse which is why i made the decision to switch over to KPM. Dont get me wrong i absolutely loved the sound of the DF system and wouldve definatly kept it if i didnt have the issues, maybe my df system was part of a bad batch but either way i was pretty pissed off having spent that much money on it.

At the end of the day choosing an exhaust setup comes down to personal preference, what one person says will differ to another person...you will always get people of are loyal to one brand and thats fine but it pays to shop around and listen to other systems...do it once and do it right the first time(lesson learnt:doh:).

[vitob2006]

If a system drones at a certain speed isn't it just a matter of changing the resonating frequency of the system? Could you just put a piece of steel or steel mesh around a part of the pipes to change the frequency so it doesn't resonate at that speed. Or put an extra resonator in or even a varex muffler would change the exhaust velocities....instead of changing to another system...surely.

why not just get one that doesnt drone? i had a varex on my VE, it was alright for a while, kinda sucked having to drive around with it quieter than stock all the time, and then when it was open it was too loud

and no, i dont have a DF system .. i've gone through all the Xforce exhausts, then went onto varex

you get what you pay for, everyone has their own budget. im extremely happy with my mutliated HM system

a lot of the crappy systems end up on the classifieds when someone went cheap and have decided to get something better after learning an expensive lesson .. i know all about it, i've gone through it 3 times

Im thinking of going DF to over come the scrapes which are mainly the cats, but who do I believe here:confused:

I’m not here to rubbish anyone’s exhaust choice or to push any particular brand, I was just pointing out my experience with clearance. It could have been as some said, part of a bad batch or there could even have been improvements in design since I brought mine.

I will say I couldn’t fault the DF system for sound or quality, I will say when the Ute was sitting on my level garage floor the front bar had 100mm clearance and the cat flange had only 75mm. The rest of the system was fine. I’ve had lower cars with worst problems but the Ute was my daily and I did need to be able to get in and out of driveways without coming in on extreme angles and listening to grinding metal.

I swapped over to a full Hurricane setup and found it much easier to live with.

My new Ute is having a full 3” system installed by CHE, so tomorrow I’ll know how suitable its clearance is. As far as sound goes, the note is important to me but drone isn’t. I only use the car to run around in city traffic, not on country highways.

[phat_calais]

we have a vz sedan that comes into work and he went and got a difilippo cat back not sure what size or steel but hes had it on there for 8 months and the rear muffler has started to crack. not sure if it came from the bad batch or not. but it does sound good with no drone compared to some other systems ive heard

[vitob2006]

But again u r missing my point. I don't care what system ppl have. Headers and exhaust are primarily to help the engine breathe better...all of them do a great job..as said in a previous post...noise is fully customised and u don't have to be loyal to any brand and even within each brand there is variation as there is in engines..what u did with urs is exactly what I am saying. U can make anything sound the way u want..and as there are those that prefer a brand there are those equally that do not. Not dependant on what u pay, its what u like....any of the major suppliers are great quality. Peace Brother

Sonny, no I'm not a salesman for KPM. :lol: Yes, waaaaay back almost 4 yrs ago now my original KPM catback with HSV headers did drone fairly badly (one of the first 3" VE catbacks they sold). When they changed the rear mufflers they used on their systems they very kindly swapped mine over for me to the new ones for only the price of the freight there and back. That still didn't cure it 100% so then as a sign of their commitment to customer satisfaction they very generously sold me a full 3" system including HPC headers at what must have been a considerable loss to them. That was well over 3 years ago now and I've been a KPM man ever since. Even an unbiased person such as Tuffie says the VE KPM system is the best he's ever heard, and he's heard plenty.

I have no idea on pre VE but several people I know with full DF sytems on their VE have had enormous clearance problems, so maybe the VE DF headers and cats hang low compared to pre VE. The newer KPM systems are extremely well tucked up. As for sound quality the full VE DF 3" system I heard sounded great at idle and on the dyno but on the road sounded slightly "off". About 8 of us were sitting out the front of Chev's when the car with it took off and we all looked at each other and commented on the "off" note.

As I said, I am not a KPM salesman and given not many people have heard one I do my bit to demonstrate the sound quality so they can make a more informed decision. I don't really give a FF :D what they choose as long as it's done with full knowledge of what's available. However, on a VE if people are considering DF just check the ground clearance first compared to Pacies or other headers.

[Wonky]

Wasn't yours Jake's old system? If so it's about three and a half years old and one of the early systems they did. They've now have greatly improved clearance now on the cats. Even my ute system on SSSLs all round clears humps that my one year older system on only SSLs didn't on the SSV sedan. I've looked at the latest KPM systems as they've been being fitted to cars at Chev's and they're even better tucked up than mine.

[vessls3]

i had a hand built twin 3inch stainless fitted to my ve ss by an undisclosed workshop in adelaide used the race series x force mufflers on it all i can say for 1800 for the headers back it sounded tuff as pulled 278rwkw on a mainline with otr exhaust and tune very stout figures for a stock 6l when i fitted my cammed 6.2 it sounded like a v8 supercar this is the best sounding exhaust ive ever heard and half the price of any of the big name brands although it had no cats but when i cammed it it was loud sounded like a drag car pulled 355rwkw with cammed 6.2 on mainline with more in it need a fuel system but was over wasting money on it i personally think the exhaust had a good part to play in the good power figures i am currently selling this exhaust as i have removed the engine from my car

[ebbett21]

I think with most of the big name brands there would be a handful of Kws between them all. I think it all comes down to personal preference in sound and dollars at the end of the day. One thing ive learnt is cheapest isnt the way to go, seems with exhausts you get what you pay for.

[vessls3]

not always true though kpm and df charge over 4000 for there exhaust how much profit do you think they would be making plenty let me tell you as long as you have good 4 into 1 headers and a properly designed x pipe you can have any straight through mufflers on it and it will make power just depends on personal sound pref and drone and i can tell you for an extra 2g i put up with drone coz that enough for another mod eg diff gear or something

I paid heaps for my DF its stainless, sounds awesome to me, best money ive spent to date on mods. Ive had 5 other systems beforehand cheap s@#t

[vessls3]

like i said it personaL pref but personal i think 4000g for a exhaust is a joke like i said i got mine hand built for 1800 or 2000 cant exactly remember and i think it sounds better than d/f and so did plenty of other people but it comes down to what you like and are prepared to pay

[Evman]

Something to remember is that with greater ground-to-exhaust clearance the system will be closer to the floorpan and that will induce a lot of heat into the cabin. I just spent $200 on VZ factory heat shields to try and reduce the heat soak from my DF system. It's only a personal nit-pick, but it still bugs me :lol:

vessls3 was that the entire system hand built for 2k or just the catback?

For the record I have a full DF system from the block to the tips (well, not the tips, they were separate) and RRP was $4080. Thanks to my mechanic I got it for much less than that though.

[vessls3]

i didnt seem to have any heat issues to be honest it was 2k from headers back car already had 1 3/4 pacies on it when i bought it

[Evman]

RRP on DF catback is around $1800, plus cats it's just under $2650. That's full stainless twin 3". The heat soak isn't an "issue" as such. A hell of a lot of people wouldn't even notice it but I drive bare foot a lot and thus pick it up. If you never drive bare foot you'd never notice the heat on this system at least.

[vessls3]

i guess the moral of the story is keep the shoes on lol

[Evman]

I guess you never wear pluggers

[vessls3]

more of the slip on type person

[vitob2006]

not always true though kpm and df charge over 4000 for there exhaust how much profit do you think they would be making plenty let me tell you as long as you have good 4 into 1 headers and a properly designed x pipe you can have any straight through mufflers on it and it will make power just depends on personal sound pref and drone and i can tell you for an extra 2g i put up with drone coz that enough for another mod eg diff gear or something
Or tri ys for good low to mid range torque...better for the street

[vessls3]

tri ys are shit

[scott w]

vessls3 saw your ss at heathcote for lsx challenge , you were running 11.8 or 11.9 did you end getting new clutch and taking it back to heathcote

[vitob2006]

tri ys are shit

hey dyno queen do ur research. peak torque and rwkw at 7000rpm....geee that's useful.....derrrrr

[jaykay]

Or tri ys for good low to mid range torque...better for the street
who else can comment on this ??? My car will not be a drag queen so the low to mid range torque is more appealing to me !!!

[VYSHSV8]

You are just driving to slow and not getting enough airflow over the pipes ya woos :lol:

[vitob2006]

at least urs looks good on the dyno....how much time does it spend on a dyno?, what 2 hours a yr how much fo u drive it? what, 2 hours a day.....at least it has high peak rwkw at 7000 rpm....what the?????? maybe call nascar and tell them to put 4 into 1s to get better dyno figures

[scott w]

i didnt seem to have any heat issues to be honest it was 2k from headers back car already had 1 3/4 pacies on it when i bought it

kpm charged me $2430 for there cat back , it makes your exhaust with only the rear x-force mufflers seem a little expensive .

[vessls3]

hey dyno queen do ur research. peak torque and rwkw at 7000rpm....geee that's useful.....derrrrr

sorry i suppose you have done your reasearch and testing on the dyno back to back testing doesnt lie put tri y on my engine made 330rwkw change to 4 in to 1 went to 355rwkw kinda tell me something when you got a 6.2 you already got a lot of torque any way so why subitute power for low down torque when you already got shit loads

[vessls3]

kpm charged me $2430 for there cat back , it makes your exhaust with only the rear x-force mufflers seem a little expensive .

not really 1800 hundred for full hand built mandrel stainless steel with racing series x force mufflers still has a centre muffler as well just no cats straight through pipes the race series x force mufflers are a hundred times better than the off the shelf systems and a a little dearer but your entitled to your opinion thats cool

[vessls3]

vessls3 saw your ss at heathcote for lsx challenge , you were running 11.8 or 11.9 did you end getting new clutch and taking it back to heathcote

yer sorted the clutch pedal out and fitted a fuel system went back ran 11.0 @ 128 should see a ten if i took a few thing out but i cbf you dont drive it on the street stripped out so y race it like that

[vessls3]

who else can comment on this ??? My car will not be a drag queen so the low to mid range torque is more appealing to me !!!

put 1 3/4 4 into1 on it you will reget it if you dont

[vessls3]

hey dyno queen do ur research. peak torque and rwkw at 7000rpm....geee that's useful.....derrrrr

sorry you should get a job on a nascar team you seem to no alot

[vessls3]

whats more i dont see to many people making 355rwkw on a mainline not a dyno dynamics with just a cam 4 into 1 are very important to sucess on ls engines they need to breath properly

[scott w]

ok , i heard you had the motor for sale .
glad your happy with the exhaust , i went with the kpm because there were a lot of people that werent happy with the off the shelf x-force systems and were selling them and getting the kpm system .

[vessls3]

yer the motor is out the car and was for sale had to turn it back to stocky for mrs to drive yer i no what you mean bout x force off the shelf thats why i had my exhaust made and used the race series mufflers and not just put an off the shelf on

[vitob2006]

All that tell u is ur peak power figure is higher. good for dyno bragging nothing else. anyway as long as ur happy.

[jaykay]

put 1 3/4 4 into1 on it you will reget it if you dont
the reason for this is ???

[vitob2006]

the reason for this is ???

No real reason mate. people go for 4-1 with 3 inch systems for sound and peak rwkw. better dyno figures. you should really hear both and experience both set ups and decide what u like. talk to a few exhaust places and performance places see if they have cars u can drive. Tri ys tend to be better for street better torque low to mid range. 2 and a half inch systems tend to be good up to 330rwkw in theory. bigger is noalways better..All makes mention on the forum a good quality but as u can tell people can emotional about them. experience a system before u by it...advice. ..don't get hooked up on dyno figures as that's just part of the full story. good luck

[255-LS1]

whats more i dont see to many people making 355rwkw on a mainline not a dyno dynamics with just a cam 4 into 1 are very important to sucess on ls engines they need to breath properly

actually GMM will guarantee you 350 rwkw from ls3 manual with full DF dual 3" and ramjet on the mainline. any ls3 manual they will do it.

good to see you're selling this alleged awesome cat back too :).

See http://www.ozgarage.com.au/season2-video/season-2-episode-9-online-exhaust-comparo, back to back comparo on an otherwise stock 6.2 Senator, done very professionally. :goodjob:

1 3/4" 4-1s actually gained a smidgin of mid-range power over tri-y. Surprisingly I'm sure to many, going from 1 3/4" 4-1s and 2.5" catback (DF?) to 1 7/8" 4-1s and 3" (DF I'm sure) catback again gained even more mid-range and plenty at the top too! Nothing in it at the bottom, but gain in midrange and even more gain at the top!! :woohoo:

May not apply to 5.7 but in my experience (admittedly very limited) it does to the 6.0 and as demonstrated by HPF certainly does to the 6.2!!

[ebbett21]

Anyone would think 7/8 headers would be for a 600 HP supercar. Why so big on a street car? wouldnt they suck or your bottom end and a chuck of the mid range. On pacemaker website they recommend only 4>1 3/4 headers only on supercharged or heavily mooded engine. HP-F do they drive a 6.2 litre on a daily basis with big as headers and a twin 3'' im thinking theres two completely comparisons a dyno and a real world driving in and out of traffic, wonder what headers is best

[SirNemesis]

1-7/8's aren't as bad as you'd think. I ran them with a cammed 5.7L, a stock 6L and then a cammed 6L, no problem at all. Plenty of low-end torque in all combinations.

[vitob2006]

There is no right or wrong answer. each have got their advantages. there are a lot of high powered engines running tri ys. my point being they should never be discounted.as an option as a lot of people do. in theory their flow characteristics makes great sense for street apps and people wanting low to midrange torque and not just chasing rwkw. There is a lot examples of NA chev engined street machines running these headers with 2.5 inch systems that are quick and don't rely on high revs to peak their power an torque. I suppose we need to experience it to appreciate it

My ute has 1 7/8" Pacies and 3" system and feels very good on the street. I'm very happy with it.

[dazzak75]

Yeah thats what he told me also but those prices do not inc fitting he said it'll be an extra couple of hundred & bout 4-6 hours depending on how busy he is, another interesting thing ive found out is that the twin 3" catbacks for ve's dont directly bolt up & do require mods to fit if running the stock cats.

scott w - speak to hp-f i ordered mine thru them @ a good price which includes fitting.

This is due to his headers being longer than standard and longer than x-force and all others, but they are good, having 1 7/8 and cats fitted as soon as the 402 is booked in for build

[DCV1NU]

Yep...i've got paccies on my car now and when my mechanic was installing them i could tell there was a good 4-5cm difference between the 2.

would be interesting to no

For VE it was from memory $995 for non hpc 1 3/4 headers(add $350 for hpc)
3inch s/s catback was $2145
3inch 200cpi high flow cats were $360each

1 7/8 headers were $1300(same cost for hpc)

[vx mad]

is there much noise difference between the twin 2 1/2" and the 3" Di Filiippeo systems. at the moment i have a twin 3" xforce system and it is loud as all hell and would like something just a bit quieter

[Benton]

3 inch will always be louder than the 2.5" if you were running identical cats and mufflers on both systems. That is just the nature of physics.

[ebbett21]

is there much noise difference between the twin 2 1/2" and the 3" Di Filiippeo systems. at the moment i have a twin 3" xforce system and it is loud as all hell and would like something just a bit quieter

I had the xforce 3'' and like you say loud and mine was barky and raspy, i didnt like the sound untill over 3000 rpm.
I have a twin 3'' difillipo now and its no where near as loud, has a nice deep rumble at idle and sounds sedate inside the cabin, no drone. Its alot louder outside then you think untill you hear someone drive it around the block, pretty nice sound all round. But for the price tag it has to be.

[Thunder]

I am about to drop huge coin on a Difilippo system , In the end it came down to 4 systems as I could only find 4 that will NOT drone, and this is main point as power can be made with just about all systems.

1. KPM looks good and should be good , but to sydney was quoted $4050 then would have to be fitted. extra for hpc

2. VCM , don't like how CATS are welded to headers , still to Sydney $3900 plus fitting. extra for hpc

3. Sureflo , great system . but quoted $4350 fitted. extra for hpc

4. Difilippo , tuner stands by it 100% although he said can achieve similar results with any of the above. $4100 fitted. extra for hpc

So for me the difilippo system is the winner just on cost . strange I know.


now for the rest , xforce , look great , but terrible DRONE , any other generic system. DRONE , any exhaust shop can fit an exhaust and it will take gas from engine out the back ,

but I just dropped 40K on a car , why fit substandard stuff to save what maybe $1000 .

This thread was about DF, so I hadn't bothered to read it.

I just thought I would clear this up. Most of the cars we quote on are new cars, not old clunkers, so we always quote ceramic coated on the extractors, unless the customer wants a cheaper option.

Our VE extractors are tight to the engine and designed so we can fit the Ballistic Race cats in the cavity that the old cat came from, which means ours has at least 25mm of extra height.

Our mufflers are custom made, 1.6mm thick steel or stainless, and the seams are TIG welded. The body of our rear mufflers is a lot bigger than any other muffler. Our system fits the standard position of the cats, which means it doesn't have to be modified if you fit our extractors at a later stage. Our systems can be made in various loudnesses as well.

It is pointless going to 1-7/8" primary extractors and then restrict them by fitting 4" body cats. The bigger the body, the more internal holes, therefore the more flow, more power, more torque, and better fuel economy (if you drive that way). A 5" body cat flows a lot more than a 4" body cat, and the cat is the biggest restriction in the system.

Imagine if you have heads & cam, or a supercharger and then being stuck with 4" body cats. After spending all that coin, you are then being robbed of power - the main reason you did it for.

In ceramic coated, our 4>1 1-3/4" extractors with 4" body cats are $1850 fitted or $1630 supplied. 5" body cats can also be fitted to these extractors.

In ceramic coated, our 4>1 1-7/8" extractors are $2200 fitted or $1980 supplied.

Our Cat back, dual 3" mild steel system is $1700 including quad stainless tips and our stainless system is $2300 including quad stainless tips. Fitted free.

Therefore, our whole system is $4150 fitted (1-3/4" ceramic coated with stainless system) or $3550 with a mild steel system.

Our 1-7/8" ceramic coated extractors, 5" body Ballistic cats and stainless system is $4500 fitted, and with mild steel system is $3900 fitted.

Our extractors and cats can also be fitted to other brands of system that fit up to the standard cats, whereas all the others require the system to be modified, the cats are restricted to the smallest possible size, and they hang low under the chassis rails. O2 sensor harness extensions are also required.

I know most places recommend DF, but that is because it is supplied as a kit and requires basic skills and tools to fit them. They have lots of happy customers, and I am not in any way discrediting their products, however, all products have their advantages and disadvantages, whether it be price, durability, sound, ground clearance, etc.

Anyway, I just wanted to clear up some discrepencies and highlight a few facts. These pictures are our 1-7/8" extractors with 5" body cats fitted. Notice how high they sit. If you look behind the cats, there is an alloy gearbox cross member with bolts that protrude. Our pipework sits under this and is nice and high. This is where the cat sits in other brands and they have to have clearance, so they hang well below the chassis rails.

Someone mentioned his front bar was 100mm off the ground - the legal limit, and the cats or extractors were 75mm off the ground - defect, and will scrape.

Look at where the chassis rails are with our extractors and cats and think which one will be the best on the street - speed humps, steep driveways, etc.

From what I've heard Di Fillipo cats sit too low to the ground and they get damaged coz of that reason?
Why is KPM so expensive? They still use peacemaker headers and cats don't they? My nexy car will have xforce 2.5" I like the racey sound of it. Haven't heard a di fillipo properly so I won
t say anything..

[Evman]

Just don't dump your car on the ground. My car is lowered but not dumped, full DF system and I've scraped maybe 3 times in a year or so that I've had it. It tends to scrape on the flanges too, which is pretty bloody solid metal anyway.

[SAMCRO]

Gotta jump in the ve with di fillip system to be able to hear it properly coz everyone says it's bloody awesome...?? How different is it to ? Now I know xforce is cheaper but I've been in the car with xforce and I love that racy sound of it..

[DCV1NU]

The DF note has a very deep beefy v8 note to it and isnt overly loud, the xforce on the other hand has a raspy & barky note to it and is loud.

Your car is a VY though Ev. I get the impression the VEs are worse with DFs for clearance.

As Boon (DCV1NU) says - the DF (and KPM) are much deeper than Xforce and don't have that raspy sound of the Xforce. If you like raspy go Xforce but I don't like it and prefer deep.

Well Wonky/Dcv1nu I will let you in a secret (where everyone can see ;) )
I am the guy who is going to buy Curtis's VE SS... Hopefully I pick it up tmrw, fingers crossed. I took it for a drive and I loved it. I know you've got kpm Wonky, but what has DCV1NU got?
What are your thoughts on curtis's ve? Great ride isn't it?

I've got Pacemaker 4-1 1 7/8 headers, surflo ballistic cats & a 3inch KPM SLC catback, yep Curtis's ve is an awsome car...all the mods he has done have been good ones so you cant go wrong.:)

btw happened to your other ve?

[SAMCRO]

The lady failed to give way & bounced me off onto the pole and the pole threw me back onto the car that was just sitting at the lights waiting to turn. The car is a statutory write off, but lucky for me I had an agreed value. very upset about my atomic baby :(

[DCV1NU]

Ah shit thats not good mate, the main thing is your ok and you've ended up with a better ve anyway.

[SAMCRO]

That's true. Thanks mate. I was gonna get some work done to it at Chev's next year (KPM & cam..) but like you said I've ended up with better ve. When I pick it up I'll come down to Chev's one Sat so hopefully I see you and your ride there..

Well i cant speak for anyone else but i love mine, and i havent had any droning at all. LS1 DAY came by chev's yesterday to have a listen to it and loved it, it comes down to personal preferance tho so listen to one in person.

Unfortunately with the software used I don’t think I can. However, Curtis himself used to maintain the website before I took over recently, so maybe he knows of a way to recover deleted stuff as he knows a lot more about the WebCommerce software than I. I’ve only needed to really touch the surface with what I’ve done so far but I know with other website software I’ve used you can restore deleted stuff.

[SAMCRO]

Thanks Wonky. Yeah I picked it up last night :):):):):):):) I LOVE IT, IT'S GREAT!!!! Well then, how about we put up a new one, I'll get some pics and write down all the staff that's been done to it (if I can remember all of it) :)
Would that be ok with you?

When the 1 7/8 pacies were fitted to my 5.7 the K frame needed to be dropped a little.

Not tge same brand but I know they aren't the easiest thing to fit.

Hey mate, is steering column disconnected and rack dropped? Only issue then is to make sure car is height enough off the ground. Also make sure you remove the metal plate that goes from chassis to firewall.

in this month's motor mag, gmm have a special on for ramjet otr, di filippo 4 into 1 long tube headers, hi flow cats and ss catback with tune
in 2.5 or 3in - $4690.

pretty good compared to some of the prices around the traps.

It's ashame GMM dont tune gas. I want the system currently $4770 for the deal but the Calais is on liquid inject and they wont touch it. :bawl:

Any of you guys know who will do the whole exhaust otr and tune for gas

I'm still yet to understand this " drone" ppl talk about.
I got a HPC pacemaker extractors 1 3/4 I'm guessing 100 cell 3" cats, no idea on brand, an a twin 3" ss Xforce with the mufflers removed. Backed onto a LS2 with a big cam an all the other bolt ons Cai etc. Everyone that has heard it loves it. I don't know about drone, just love hearing the different notes depending on how I drive and what the noise rebounds off, like tunnels an cliff faces etc

What's not to understand? You don't know what it is or something like that??

[rteuma]

On my VY SS11 i've got Pacemaker 4-1 extractors, twin 2 & 1/2" difilippo exhaust with twin high flow cats. This was installed about 2 years ago.

I love the sound of this exhaust and don't need to go to twin 3" cos im running a stock LS1 but i had 2 issues.

1. I had the rear muffler removed cos it wasn't loud enough with it in, it's louder now and it doesnt worry cops. So i wasted money on the rear muffler etc.

2. The clearance under the diff is terrible and i've had to fabricate a bash plate for the exhaust so i dont dmaage it.

other than that, i always get comments on the note it makes especially from 3000RPM onwards :D
