Gibson 04-08 Ford F-150 FX4 5.4L 3in Cat-Back Single Exhaust - Aluminized

This Gibson cat-back exhaust system is built with aluminized, mandrel-bent tubing, a smart choice for resisting corrosion and ensuring a solid fit on your 2004-2008 Ford F-150 FX4 with the 5.4L engine. It's designed to exit behind the rear tire, offering a clean look and a more aggressive sound when you step on the gas, while keeping things quieter inside the cab during normal driving. You can expect improved acceleration and better power for towing and passing, especially in the low-end RPM range where it matters most for trucks.

The system features Gibson's Superflow muffler, which uses baffles and chambers instead of internal packing to manage sound and exhaust flow. This design helps achieve noticeable gains in torque and horsepower, often between 1800 and 3000 RPM, without creating excessive interior drone. The polished stainless steel slash-cut tips add a nice finishing touch to the rear of your truck.

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 makes for a hassle-free upgrade that looks professional once installed. Gibson backs this system with a Lifetime Limited Warranty.
