You may be right, I don't know so that's why I am asking. Is their any actual proof that a 2.5" dp is not sufficiant for a N/A car? I see this alot on here so that's why I am asking. Im still running a stock dp with the ubend gone. I see no KR on 11 psi. What benefits would I see switching to a 3" pipe?

If you weren't inter-cooled you'd NEED a 3" downpipe.

If you wanted to run more boost, get some headers and drop again.

It's a low 13 sec car as it is and if I do anymore to this car it will be demod and turbo. I regret not going turbo right off the hop. Oh well.

yes. gm is retarded for making a restriction like that in the exhaust system. they did it for the o2 sensor protection but mine has been fine without any protection whatsoever
