Gibson gib12213

The Gibson single-side cat-back exhaust for 2004–2010 Infiniti QX56 (5.6L) is an aluminized system that improves acceleration, hill climbing, towing and passing power while exiting behind the rear tire. Dyno testing shows stronger low-end torque and horsepower between 1800–3000 RPM, with typical gains of 10–15 hp and 15–20 lb‑ft. It bolts on with included hardware and factory-style hangers, uses a baffled Superflow muffler to limit interior drone, and finishes with a polished slash-cut tip under a lifetime limited warranty.
