The Gibson single-side cat-back exhaust for 2002–2005 Chevrolet Avalanche 1500 (5.3L) boosts low-end torque and acceleration for towing, passing and hill climbing. Dyno-tested gains average 10–15 hp and 15–20 lb‑ft in the 1800–3000 rpm range. Stainless mandrel-bent tubing, a baffled Superflow muffler and polished slash-cut tip deliver an aggressive sound with minimal cabin drone. Includes hardware and factory-style hangers for a bolt-on, no-weld install and a lifetime limited warranty.
