I'm taking my car in to the muffler shop monday to get some new exhaust, my old intermediate pipe had a hole in it. (so I ripped it all off and drove with open headers the past couple days hehehe) now my question is...should I replace it with the normal 2.25" pipe, or should I get a bigger one made, like 2.5" or 3"? Ive heard that bigger pipes actually rob the car of low end power, is this true? I need to get my facts straight before I spend my money.
