The Gibson single-side cat-back exhaust for 2001–2006 Chevrolet Silverado 2500 HD LS (6.0L) is a stainless steel cat-back system that boosts acceleration, towing and hill-climbing power while exiting behind the rear tire to reduce cabin noise. Dyno-tested for strong low-end gains—typical increases of 10–15 hp and 15–20 lb‑ft—this bolt-on kit includes mandrel-bent tubing, a baffled Superflow muffler for aggressive tone with minimal drone, polished slash-cut tip, factory-style hangers and a lifetime limited warranty.
