The Gibson single-side cat-back for 2011–2013 Ford F-150 King Ranch 5.0L is an aluminized system tuned to improve acceleration, towing and low-end torque. It exits behind the rear tire and offers quieter in-cab operation than many aftermarket mufflers. Expect average gains around 10–15 hp and 15–20 lb‑ft of torque. Installation is bolt-on with factory-style hangers and polished tips, backed by a lifetime limited warranty.
