i see a lot of people running mainly 2.5" downpipes, and then I hear the craze is the 3". I did try a 3" exhaust and it did help out some on my setup (over my old 60mm greddy) just felt like better spool up time and better high end, but im curious if the change is as severe or more severe from stepping up to a 3" downpipe.

anyone done dyno results? im not looking for 500whp but just curious how much of a difference it has made it some peoples cases, or if i shouldn't even worry about the hassle right now. thanks.

 

take off the DP completely and find out. no exhaust is the best eshaust (for turbo)

 

agreed

 

Corky Bell 4 shizzle! hes right! open dp is da bomb yo! ok thats enough of that. but seriously, while alot of people say the f-series engine needs backpressure somewhat to seal, i say fu*k exhaust systems. the only thing is you gotta shut your car off and enter stealth mode everytime you see a po-po.

I think its worth the 3" dp unless you want a low/mid grade setup.
