dual exhaust for vt II s commodore

[nathan549]

i want to have dual exhaust (tail pipes both sides) on my v6 commy. im woundering wats the best system to get?? and also what would suit a v6 more 2.25 inch or 2.5 inch. heard alot of ppl saying 2.5 inch is to big for a v6. just wannting to know your guys oppinions .

 

[stevesvx2001]

you want 2.25 or even 2 up to the cat cause it makes more back presure and creates more power

 

[nathan549]

anyone else have oppinions?? what type of system should i be looking at getting?

TWIN 2.5" is huge for an (i'm assuming) stock Ecotec mate. You will most likely lose more power than you will make.

Single 2.5" is fine. If you want the twin tips for the look, just get them to dummy up a pipe with a tip on it for the other side.

yeh il be going 2.25 not 2.5

Twin? I still wouldn't even put a twin 2.25 on it. Single 2.5" is pretty sweet.

i have pacemaker headers, twin cats that go into muffler just before diff then into single over diff into resinator, all is 2.5, was told it wasnt possible to go twin exhaust coz there is no exhaust well to go other side of fuel tank, unless ur pocket is really deep!!!

That's pretty much the exact set up i would go on a 3.8^^^^^ I had the same on my old V6, except it was single from the cat. Sounded alright as far as a V6 went too.
