when i added my bassani x it sounded like a nascar, i'm so tempted to remove the cats... i'm not saying this because it's my exhaust but it's the best i've heard. as your driving through the RPM's around town it literally sounds like a nascar with a nice exotic sound (not raspy). it's hard to explain but i love it. i've got more compliments in the past week then in the past 6 months when i just had my stingers and stock H. oh and when you go WOT it's just scray
