3" exhaust sorry

 

It depends on how much boost and what type of boost your running. If your turbo'ed then you probubly want to run a full 3" exhaust. If your supercharged, then 2.5" all the way back will be enough for up to around 10psi. That's what i'm running. You might see some gains if you go 3" with that setup, but the low end loss of power may not be worth the peak gains.
