Gibson 99-02 Chevrolet Silverado 2500 Base 6.0L 1-5/8in 16 Gauge Performance Header - Ceramic Coated

Starting with 3/8 inch thick, laser-cut port flanges, these Gibson Performance Headers are built to handle the heat and pressure of your 6.0L engine. They're designed to be a direct replacement for your factory exhaust manifolds, using the stock crossover pipe and OEM-style connections, so you won't need any welding to get them installed. This means a cleaner installation and a solid seal that resists warping and leaking, even under tough conditions.

The 1-5/8 inch primary tubes are made from 16-gauge 409L stainless steel, which is a well-built material that holds up well over time. They're also treated with a high-temperature ceramic coating that can withstand temperatures up to 1300 degrees Fahrenheit. This coating helps keep underhood temperatures down, which can lead to a cooler operating engine and improved performance. Gibson tunes these headers on the dyno to help your engine breathe better, aiming for more usable horsepower and torque, especially in the low and mid-range RPMs you use most often for highway driving.

These headers fit a wide range of trucks and SUVs, including models like the Chevrolet Silverado 2500, GMC Sierra 2500, and Cadillac Escalade from the late 90s and early 2000s. They're also 50-state street legal, meeting EPA and CARB requirements, so you can install them with confidence. You'll get premium gaskets and hardware included in the box to ensure a complete installation. Gibson backs these headers with a lifetime limited warranty, giving you peace of mind with your purchase.
