Gibson 00-05 Ford Excursion Limited 5.4L 1-1/2in 16 Gauge Performance Header - Stainless

Gibson is well-known for exhaust components that help your engine perform better. For your 2000-2005 Ford Excursion with the 5.4L engine, these performance headers are a solid choice to help your truck breathe easier. They are designed to replace your factory exhaust manifolds directly, using the stock crossover pipe, so installation is straightforward with no welding required. The 1-1/2 inch, 16-gauge tubing is mandrel-bent to ensure smooth airflow, which helps the engine produce more usable horsepower and torque, especially at the low and mid-range RPMs you use most often for highway driving. This improved breathing can also lead to cooler engine operating temperatures.

These headers are built tough with 3/8 inch thick, laser-cut port flanges that resist warping and leaking, ensuring a solid seal. They are constructed from heavy-duty 409L stainless steel tubing, which holds up well over time. Gibson includes premium gaskets and hardware to make sure you have what you need for a complete installation. They use OEM-style connections, making them compatible with your existing exhaust system. These headers are street legal in all 50 states and meet EPA and CARB requirements, so you can install them with confidence. They are also well-suited for both lowered and raised vehicles, and for street or off-road use.

Because these are a direct replacement for your factory manifolds and use OEM-style connections, they are designed to fit right without modifications. They are also designed not to affect your factory warranty. Gibson backs these headers with a lifetime limited warranty, giving you peace of mind with your purchase.
