this thread is about aftermarket vs. stock exhausts. it ends up with me and a few guys vs. a daperformance rep and his buddy who says: "Ace isnt a mechanic and apparently knows little of how cars work." and "Ace is not smarter on this fact and is really showing his stupidity. " So, if you like me, if you don't like me... it's worth the laughs, and maybe you'll learn something.
