The Gibson single-side cat-back exhaust for 2007–2009 Toyota Tundra SR5 (4.7L) is an aluminized, bolt-on system tuned to boost acceleration, hill climbing and towing capability while exiting behind the rear tire. Dyno results show gains in low-end torque and horsepower between 1800–3000 RPM, typically 10–15 hp and 15–20 lb‑ft. The system includes factory-style hangers and hardware, a baffled Superflow muffler for minimal interior drone, a polished slash-cut tip, and a lifetime limited warranty.
