Turbo back exhaust system with muffler and Sinister tip off my 21 Ram 2500 Laramie Crew Cab 6.7 Cummins. About 6k on the system. All mating points have been cleaned. Just need a few clamps, mount and go. Nothing wrong with it. Sounds awesome, not too loud, and NO cabin drone. Buy now and save. Paid $1200 for this system.
