Hi All,
I'm getting a cam and 4.11 gears installed tomorrow, but its got me thinking about its support system, the exhaust.
I currently have pacemaker 4-1 1 3/4 headers with magnaflow cats (fitted 2007). Will I see a worthwhile gain in HP and torque of I change to the Sureflow 4-1 1 7/8's with 5" body 100 cpi cats?
I also have a problem with the current headers hanging quite low.
$1490 headers and cats
$450 black ceramic coat
$??? To fit to existing exhaust and touch up tune
Your thoughts would be appreciated.
