Hi, I just got my first supercharged 03 Grand Prix. Im looking to do the intake, exhaust, and a smaller supercharger pulley. Im on a teenager budget unfortunately. So not the top of the line equipment, but no garbage. Basically I want a sleeper, but something with a throaty intake and supercharger whine. The exhaust I plan on putting a remote controlled butterfly in it, that way I can have it stock and practical or obnoxious and frowned upon "HA-HA" Can someone point me in the right direction for an intake? Then the smaller pulley, whats the trouble with a knock sensor or something? Is it better to go with one of the smallest available or something more mid range? As far as the exhaust I can figure that out, input is appreciated though. Thanks for the help!
