The Gibson Dual Extreme cat-back exhaust for 2010–2013 Chevrolet Silverado 1500 LS (4.8L) is an aluminized system built for aggressive tone and presence. With angled exits behind the rear tires and polished stainless tips, it delivers dyno-tested gains typically around 15–20 hp. The Superflow CFT muffler produces a mean sound while minimizing interior drone. The complete kit includes hardware for bolt-on installation and comes with a lifetime limited warranty.
