Gibson 05-08 Ford F-150 King Ranch 5.4L 2.5in Cat-Back Dual Split Exhaust - Stainless

This Gibson cat-back exhaust system is built with 2.5-inch mandrel-bent stainless steel tubing, which helps reduce backpressure compared to the factory setup. It’s designed specifically for the 2004-2008 Ford F-150 King Ranch with the 5.4L engine, and also fits the Lincoln Mark LT from 2006-2008. The dual split rear exit with polished stainless steel slash-cut tips gives your truck a more aggressive look out back.

Inside, the Superflow™ muffler uses baffles and chambers instead of internal packing, which contributes to a deeper, more aggressive exhaust note without excessive interior drone. This design also helps maintain a comfortable cabin environment, even under load. You can expect a noticeable improvement in torque and horsepower, with typical gains averaging between 15-20 horsepower. The exhaust sound gets louder when you're towing, letting you know it's working hard.

Installation is straightforward thanks to the hassle-free, bolt-on design; no welding is required. The system is constructed from durable stainless steel to resist corrosion, and it's backed by a lifetime limited warranty from Gibson. This cat-back system is designed to work with most bumpers, roll pans, and trailer hitches.
