The Gibson single-side cat-back exhaust for 1999–2001 Chevrolet Silverado 1500 LS (4.3L) improves low-end torque and throttle response for towing and everyday driving. Dyno-tested results show average gains of 10–15 hp and 15–20 lb‑ft in the 1800–3000 rpm band. The stainless mandrel-bent system features a baffled Superflow muffler, polished slash-cut tip and factory-style hangers for an easy no-weld bolt-on installation, quieter cabin feel, and a lifetime limited warranty.
