The Gibson single-side cat-back exhaust for 1987–1992 Ford F-150 4.9L is a bolt-on stainless system that exits behind the rear tire to improve acceleration, towing and passing power. Dyno-tested to boost low-end torque and horsepower, it commonly yields about 10–15 hp and 15–20 lb-ft. Features include mandrel-bent stainless tubing, baffled Superflow muffler, polished slash-cut tip, factory-style hangers and a lifetime limited warranty.
