The Gibson single-side cat-back exhaust for 2007 GMC Sierra 2500 HD Classic SL (6.0L) is a stainless cat-back system that enhances acceleration, towing and passing power while routing exhaust behind the rear tire to reduce cabin noise. Dyno-tested to yield low-end increases—typically 10–15 hp and 15–20 lb‑ft—this bolt-on system features 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.
