907mge is on a distinguished road
Default Is exhaust too big?

I have a hks 3in turbo exhaust on my 7mge. From what i have read it seems 2.5in is the way to go because back pressure is needed. But if i have a pacestter header with a 2in collector how is that not enough restriction for back pressure? I also have a 3in high flow cat on it.
