The Gibson single-side cat-back exhaust for 2003–2004 Nissan Xterra SE (3.3L) is an aluminized, bolt-on system tuned to improve acceleration, hill climbing, towing and passing power while exiting behind the rear tire. Dyno results indicate stronger low-end torque and horsepower between 1800–3000 RPM, with average gains around 10–15 hp and 15–20 lb‑ft. Includes factory-style hangers and hardware, a baffled Superflow muffler for reduced cabin drone, polished slash-cut tip, and a lifetime limited warranty.
