MitsuStyle - View Single Post - exhaust setup

It isn't going to make much of a difference. On a car putting down around 350whp, you might gain only 5 whp by going from a 2.5" exhaust to a 3" exhaust. On a car making 300whp or less, it might hard to even see a power gain, unless you do magazine style dyno runs.

I would wait until your current one falls apart or you go with a bigger turbo.
