The Gibson Dual Extreme cat-back exhaust for 2009–2010 Ford F-150 FX4 5.4L is a stainless bolt-on system positioned behind the rear tires for an aggressive look and a powerful exhaust note. Mandrel-bent tubing and a baffled Superflow CFT muffler deliver a mean tone while minimizing interior drone. Dyno-tested for typical 15–20 horsepower gains; installation requires no welding and the system carries a lifetime limited warranty.
