The cat-back is brand new, not even a month old. The reason for selling is to try more than one company. The cat-back with the device is new for 3800, with a bumper exit for two mufflers. Put your offer, and I won't disappoint the serious buyer. It comes with two remote controls for the muffler, the second is still in its plastic, unopened. Since I installed it, the car has mostly been used for commuting from home to work. I haven't taken it out much. I installed it before Eid, and the stickers are still there too.
