The Gibson single-side cat-back exhaust for 2001–2006 Chevrolet Silverado 2500 HD LS (6.0L, 4in) enhances low-end torque and towing capability. Dyno-tested results typically show 10–15 hp and 15–20 lb‑ft gains between 1800–3000 rpm. This stainless mandrel-bent system features a baffled Superflow muffler, polished slash-cut tip and factory-style hangers with included hardware for an easy no-weld bolt-on installation, reduced in-cab drone and lifetime limited warranty coverage.
