The Gibson Super Truck cat-back for 1999–2004 Ford F-250 Super Duty Lariat 5.4L delivers a deep, race-style rumble with dual tailpipes that exit in front of the rear tires and stainless tips. Dyno-tested to improve acceleration and add typical gains of 10–15 hp and 15–20 lb‑ft, it uses mandrel-bent tubing and a baffled Superflow muffler. Bolt-on installation requires no welding; not recommended for towing and noise may exceed 95 dB. Includes a lifetime limited warranty.
