The Gibson single cat-back exhaust for 2003–2006 Hummer H2 (6.0L) is a stainless steel, bolt-on system that exits straight out the rear and finishes with a polished slash-cut tip for a professional look. It uses a baffled Superflow CFT muffler and mandrel-bent tubing with factory-style hangers for easy install, offers minimal interior drone and typical gains of 5–10 horsepower, and is backed by a Lifetime Limited Warranty.
