Damn, i cant imagine how much louder the Race version is. I have the sport version with stock xpipe and test pipes and it is starting to get too loud for me. Do you have stock x-pipes? Any test pipes? I might have to put up my exhaust for trade for something a little quieter. Not sure if theres anything else i could do besides going back to the stock axel back.
