The Gibson Dual Extreme cat-back exhaust for 1998–2003 Ford F-150 XL 4.2L is a stainless bolt-on system that exits behind the rear tires at an aggressive angle for a bold street presence. Mandrel-bent tubing, a baffled Superflow CFT muffler and polished stainless slash-cut tip produce a mean sound with limited interior drone. Dyno-tested gains average 15–20 horsepower; easy clamp-on installation, no welding, and backed by a lifetime limited warranty.
