well i have a cheap muffler on there now just for looks.... stock header and piping w/ stock resonator and Cat. The car sounds real clean. Its not loud at all.... in fact I wouldnt mind it being just a little louder lol. Like i said I really do not want to do anything to my D17 because its not worth it. Im buying these tomorrow....



Im excited about those seats... i think they are gonna look real nice in there.
