Mafless Edit, Now Exhaust????

[VT GEN3]

I have a VT2 SS M6.

I had a mafless edit done on a completely standard car, car did 195rwkw.

If I add 2.5inch twin system, what will be the new RWKW????

Exhaust guy says 15rwkw. So that would be 210rwkw??? Is he telling porkies or is he on the money

Best way to find out is to put it on the Dyno

Yeah as said best to get get it re-dynoed.

Im seeking an educated guess. Dont wanna put it on, whack it on the dyno for a 1rwkw gain.

Then I cant go to the exhaust guy and say "told ya", he will say I got the cash, who cares.

Mate, you're having a go everywhere all at once, it is very confusing!

As I have said, you won't go backwards in putting on a less-restrictive exhaust. The actual kw gain may vary significantly car to car, but improvement will be there and will be felt when driving.

Cheers,

prob should have done all the mods first, then a maffless edit.

15rwkw is possible - a little on the high side perhaps? Depends if you full zorst or cat back only.
I found th exhaust smoothed out my dyno graph more than anything. I gained 7rwkw, however i was more happy with the torque line not being so jaggered

My VYII SS Ute did 207rwkw with:


DF twin 2.5"catback exhaust
GTS Maf pipe
MCAI with 2 hole mod
PULP 95RON
Maf edit


So I reckon that you should be able to get your 210kW no probs...
