Thread: Trade: GMPP exhaust for ZZP newest catback

I've got the GMPP catback and it's too loud for me to pass inspection. I'd like to trade for the newest ZZP catback since that should be quieter I hope. I need the 2.5". Would prefer this to be local so we don't have to deal with shipping. I'm located in MA and can travel around New England, maybe NY close to the boarder. Would also trade for the borla catback.
