💐Peace be upon you, I hope to God that you are in full health and wellness. I have a complete factory exhaust system from under the exhaust pipe to the end, very little mileage, like new, fits Sierra 1500 regular cab. (There is welding on the large middle muffler due to cutting from both sides of the factory rear exhaust system for removal and installation) 🔴 (Reason for selling: installing an electronic sports exhaust system and no longer needing this one) 1- The three catalytic converters are in one piece, no welding, in factory condition. 2- Includes the large middle muffler, it was previously removed and installed on the factory exhaust system. 3- Includes the rear muffler (in factory condition). Complete GMC Sierra exhaust system, model 2016 (GM) original. Fits 5.3L engines✅Sierra 1500. Does not fit 6.0L engines❌
