i would go with borla, its a little expensive but its worth it

basically any aftermarket performance exhaust system will net you the same power. go to yotube and just start searching for different sound clips and decide what one you like best. i can give you some direction where to start if you tell me what you want. loud as crap? loud when WOT but calm when cruising and idling?

yeah borla sounds great but as u said a little expensive. i might design the same in borla dealer in my hometown which will cost cheaper and have the same sound. so what do u think of that??
