The Gibson Dual Sport cat-back exhaust for 2001 Chevrolet Silverado 3500 (8.1L) is a stainless system with a 3.0in/2.5in routing that exits behind the rear tire for improved style and to avoid interfering with a tow trailer. Dyno-tested to add roughly 10–15 horsepower and 15–20 lb‑ft of torque, it uses a baffled muffler for minimal interior drone, polished slash-cut tips, mandrel-bent tubing and includes all hardware for simple bolt-on installation and a lifetime limited warranty.
