if you car is faster by anychance....its because your saving weight.
600 dollars hahaha. You can get a muffler delete, a resonator, and new tips for less then HALF the price. a muffler shop can custom fabricate a cat-back system for that price.
or just get the AA tune instead for $500 and you'll actually make 10-15+ more hp. I'd rather have that than more noise.
