Gibson 07-14 Ford Expedition EL XLT 5.4L 3in Cat-Back Single Exhaust - Stainless

Gibson has been making exhaust systems for a long time, known for their focus on performance and sound. This 3-inch cat-back system is specifically built for your 2007-2014 Ford Expedition EL XLT with the 5.4L engine. It's designed to give you a noticeable boost in acceleration, towing, and passing power, especially where you need it most – at lower RPMs. Dyno tests show this system can add between 10-15 horsepower and 15-20 lb-ft of torque, primarily in the 1800 to 3000 RPM range, which is great for hauling or climbing hills.

What sets this Gibson system apart is its Superflow™ muffler, which uses baffles and chambers instead of internal packing. This design helps reduce interior drone, so you get an aggressive exhaust note outside without it being overwhelming inside your cab. The tubing is made from mandrel-bent stainless steel, ensuring consistent diameter for optimal flow and corrosion resistance, and it exits behind the rear tire with polished stainless steel slash-cut tips. Installation is straightforward thanks to the bolt-on design, which uses factory-style hangers and includes all necessary hardware, meaning no welding is required.

This cat-back exhaust is a solid option if you're looking to get more out of your Expedition's engine, especially for towing or heavy loads. It's backed by a Lifetime Limited Warranty from Gibson, giving you peace of mind with your investment.
