The Gibson single-side cat-back exhaust for 2001–2006 GMC Yukon Denali (6.0L) improves low-end torque and drivability for towing and everyday use. Dyno-tested figures typically show 10–15 hp and 15–20 lb‑ft gains at 1800–3000 rpm. The stainless mandrel-bent system pairs a baffled Superflow muffler with a polished slash-cut tip, includes factory-style hangers and hardware for a no-weld bolt-on installation, reduces interior drone and carries a lifetime limited warranty.
