i know its not a camaro but has any body got the powerdyne/rksport supercharger for their 3.8 camaro or firebird and how much horsepower did it give you and would i need to get a freeer flowing exhaust before i install it

 

firebirds are welcome too!! yes, you will have to get at least a good cat back, for you to get the full benifit from the S/C

welcome to the forums!!
