So Im currently in the market for a turbo back exhaust system. First off, what I am looking for is an exhaust with the nastiest deepest throaty type of I dont give a **** if everyone knows I got some mad boost kind of sound. Second, I'm looking at performance and power gains. I have narrowed my decision down to 2. GHL or Turbo XS. I know a few people here own these two systems. Please, fill me in on which one has the most badass sound and performance. Thnx and have a nice day.
