The Gibson single-side cat-back exhaust for 2001–2003 Chevrolet Silverado 1500 HD LS (6.0L) increases low-end torque and acceleration for towing and passing tasks. Dyno-tested average gains are 10–15 hp and 15–20 lb‑ft between 1800–3000 rpm. Built from stainless mandrel-bent tubing with a baffled Superflow muffler and polished slash-cut tip, it includes hardware and factory-style hangers for an easy bolt-on, no-weld installation and a quieter cabin experience backed by a lifetime limited warranty.
