Fits all 1999-2005 4.8L, 5.3L and 6.0L GM Trucks and SUV's
Keeping up with GM performance applications, we have released our newest exhaust header. We have taken the time to ensure that these are the best headers for the newest GM trucks. Extreme effort was put forth towards proper fitment, durability, and performance. They have produced gains of 22 horsepower and 25 ft./lbs. of torque on a stock 5.3L V-8. These exhaust headers are designed to work with all three V-8 engines. They will work on both two and four wheel drive. Features: 1 3/4" Primary Tubes; HPC Ceramic Coated; Emissions Compatible; Laser cut flanges for accurate gasket seal; Includes headers, gaskets, bolts, and installation instructions. ** Does require some installation welding as documented in the installation instructions.
