Gibson GP500S-C 1-5/8 in. Ceramic Coated Performance Headers for Select 2002-2006 GM (6.0L)

Fits select 2002-2006 Cadillac Escalade, Chevrolet Silverado/Suburban, GMC Sierra/Yukon, and Hummer H2 (6.0L).

Gibson Performance headers are dyno-tuned to deliver increased low- and mid-range horsepower and torque, making them ideal for heavy-duty towing, street performance, and off-road use. Designed as a direct bolt-on replacement for restrictive factory manifolds, these headers maintain compatibility with your stock crossover pipe and OEM-style connections without the need for cutting or welding.

Constructed from mandrel-bent 16-gauge 409L stainless steel, the 1-5/8 inch primary tubes ensure smooth exhaust gas scavenging and improved engine breathing. The heavy-duty 3/8-inch laser-cut flanges provide a superior seal to prevent warping or leaking under high thermal stress. The high-temperature ceramic coating is rated up to 1300°F, effectively lowering under-hood temperatures while protecting the headers from corrosion.
