The Gibson Dual Sport cat-back exhaust for 1987–1992 Ford F-150 Custom 4.9L is a stainless split-rear system that exits behind the rear tire for a distinctive look while maintaining towing compatibility. Dyno-tested to add roughly 10–15 hp and 15–20 lb-ft of torque, it delivers a deep authoritative tone with minimal in-cab noise. Installation is bolt-on with included hardware and factory-style hangers, and the system carries a lifetime limited warranty.
