The Gibson Dual Extreme cat-back for 1999–2002 Ford Expedition XLT 4.6L is a bolt-on stainless system engineered for bold looks and an aggressive exhaust tone. Dyno-tuned for street performance with typical gains of 15–20 hp, it combines mandrel-bent tubing, a baffled Superflow CFT muffler and polished clamp-on tips. The angled rear exit enhances stance, installation requires no welding and Gibson backs it with a lifetime limited warranty.
