Gibson single-side cat-back exhaust for 2010–2013 GMC Sierra 1500 SL 5.3L is a stainless cat-back system that improves acceleration, towing and passing power while exiting behind the rear tire and offering quieter cabin sound than many aftermarket systems. Designed for low-RPM torque increases, the system uses mandrel-bent stainless tubing and a baffled Superflow muffler to limit interior drone. It includes polished slash-cut tip, factory-style hangers and all necessary hardware for an easy bolt-on, no-weld install, backed by a lifetime limited warranty.
