The Gibson single-side cat-back exhaust for 1998–2003 Ford F-150 XL 5.4L is an aluminized cat-back system that improves acceleration, low-end torque and towing response. It exits behind the rear tire, reduces in-cab noise, and delivers measurable low-RPM torque and horsepower gains. Bolt-on installation uses factory-style hangers and includes a polished slash-cut tip and a lifetime limited warranty.
