Gibson single-side cat-back exhaust for 2010–2013 GMC Sierra 1500 SLE 4.8L is a stainless cat-back system that increases acceleration, towing and passing power while routing exhaust behind the rear tire and limiting cabin noise for a refined driving feel. Targeted low-end torque improvements come from mandrel-bent stainless tubing and a baffled Superflow muffler that reduces interior drone. The kit includes a polished slash-cut tip, factory-style hangers and all hardware for a bolt-on, no-weld install with a lifetime limited warranty.
