Gibson 05-06 Ford F-250 Super Duty XL 5.4L 1-5/8in 16 Gauge Performance Header - Stainless

You're getting a pair of Gibson Performance Headers, designed specifically for your 2005-2006 Ford F-250 Super Duty with the 5.4L engine. These headers replace your factory exhaust manifolds, aiming to help your engine breathe more freely. By improving exhaust flow, they can contribute to more usable horsepower and torque, particularly at the lower and mid-range RPMs you use most often during highway driving. This can also lead to a cooler operating engine temperature, which is always a good thing for longevity and performance.

Gibson builds these headers from heavy-duty 16-gauge 409L stainless steel tubing, which is known for its resistance to corrosion. The port flanges are a solid 3/8 inch thick and laser-cut, which helps prevent warping and ensures a good seal to avoid leaks. They're designed as a direct replacement, using OEM-style connections so you won't need to do any welding. The mandrel-bent tubing maintains a consistent diameter throughout, which is crucial for smooth exhaust flow. This means they fit right in with your stock crossover pipe, making installation straightforward without affecting your factory warranty.

These headers are also 50-state street legal and meet EPA and CARB requirements, so you can install them with confidence. They're well-suited for both lowered and raised trucks, whether you use it for street cruising or off-road adventures. You'll also find that premium gaskets and all the necessary hardware are included in the box, so you have what you need to get them installed. Gibson backs these headers with a lifetime limited warranty, giving you peace of mind with your purchase.
