Product Details

Gibson has been making exhaust components for a long time, and they're known for building parts that help your engine breathe better. This performance header is designed to replace your factory exhaust manifolds on a wide range of trucks and SUVs, including models like the 2002-2006 Cadillac Escalade, 2003-2006 Chevrolet Silverado, and 2002-2006 GMC Sierra. By improving how your engine exhales, these headers can help increase usable horsepower and torque, especially in the low and mid-range RPMs you use most often during highway driving. They also help keep your engine running cooler.

These headers are constructed from tough 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 to ensure they lay flat against the cylinder head, preventing warping and leaks. Gibson uses mandrel-bent tubing throughout, meaning the inside diameter stays consistent through the bends, allowing for smoother exhaust flow. They're designed to connect directly to your stock crossover pipe, and installation is straightforward with no welding required, using OEM-style connections. Premium gaskets and hardware are included to make the job easier, and the whole assembly is backed by a Lifetime Limited Warranty.

This header system is street legal in all 50 states and meets EPA and CARB requirements, so you can install it with confidence. It's also designed to work well on both lowered and raised vehicles, for street or off-road use, and will not affect your factory warranty.
