Product Details
When you're looking to get more out of your truck's engine, a set of Gibson Performance Headers like this one is a solid step. This particular header is designed to replace the factory exhaust manifolds on a range of GM trucks and SUVs, including models like the 1999-2002 Chevrolet Silverado 2500, 2001-2002 GMC Sierra 2500 HD, and the 2002 Cadillac Escalade. By improving how your engine breathes, these headers can help increase usable horsepower and torque, especially at the lower and mid-range RPMs you use most often during highway driving. They're also designed to help keep engine temperatures cooler.
Gibson builds these headers from tough 16-gauge 409L stainless steel tubing, which is known for its resistance to corrosion. The port flanges are a beefy 3/8 inch thick and laser-cut to ensure a flat surface, which helps prevent warping and leaks down the road. Everything you need for installation is included, such as premium gaskets and hardware, and they use OEM-style connections so they'll bolt right up to your stock crossover pipe. This means no welding is required for installation, making it a more straightforward job. These headers are also 50-state street legal, meeting EPA and CARB requirements, and they won't void your factory warranty.
These headers are a good option whether your truck is lowered or lifted, and they're suited for both street and off-road use. Gibson backs these headers with a Lifetime Limited Warranty, giving you peace of mind with your purchase.
