Hello all first post and I read as many things as I could on dual exhaust but I do know more of what I want (with possible suggestions of course!). I recently got my car fixed and requested to get a GT dual cutout bumper and since it was recently completed, I decided I needed to find a dual exhaust setup. I found a Pypes set from this site and then found a MAC set from here. I'm looking partial performance partial sound. I was wondering if either a. this forum has worked with either of those sites (good/bad/indifferent) or if there are other sites I should check out (like AmericanMuscle.com) or other brands worth checking out. I am looking under 500 if that helps.
