2016 waiver Automatic Gasoline I have a BTM catback without the Y-pipe for the Sierra. It fits models from 2007 to 2018. - Dual tips. Used for 5 months, no backfiring or overheating. Very clean, selling complete with the unit and two remotes. The catback is currently installed on the vehicle. - Asking 2800, non-negotiable to avoid awkwardness.
