High Temperature Black Coated Exhaust Headers 2002–2013 Silverado Sier

Certified Automotive Experts exhaust headers are engineered for a high-performance bolt-on replacement of factory cast iron manifolds on 2002–2013 Chevrolet, G, and Cadillac full-size trucks and SUVs equipped with LS-style 4.8L, 5.3L, 6.0L, or 6.2L V8 engines. These fit engine and exhaust systems that use a beveled Y-pipe connection on the right side manifold flange. Built from premium 304 stainless steel these headers are designed to improve exhaust flow, increase horsepower, and withstand high-temperature, high-demand environments.

Each set features 1-5/8” mandrel-bent primary tubes, TIG-welded seams, and 3/8" thick laser-cut flanges for durability and leak prevention. The passenger (right) side flange is a ball-and-socket style (beveled) flange, designed to mate with the factory Y-pipe that use a donut-style gasket. This design is standard across nearly all 2002–2013 GM LS truck and SUV platforms, but some rare variations may use a flat flange on the right side—please check your vehicle's flange style before purchase for best fitment assurance.

These headers are compatible with standard exhaust configurations and factory-style cylinder heads, offering a seamless installation with improved throttle response and aggressive sound. Ideal for daily drivers, towing builds, and mild performance upgrades.
