Hi, I would be interested in selling my 5 day old B&B cat back resonator version. I had it installed Thursday and it is not quite loud enough for me. I would be open to trading/buy an X pipe. I would rather sell this and buy a new X pipe version than just buy a new X pipe from Boat. I will ship in the original box or you are welcome to pick it up in Louisville, KY. Email me at [email protected] $750 will do it.
