Upgrade your compatible GM truck or SUV exhaust system with Certified Automotive Experts Exhaust Headers, designed as a high-performance bolt-on replacement for factory cast iron exhaust manifolds. These headers are intended for select 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.
Constructed from 304 stainless steel, these headers feature 1-5/8-inch mandrel-bent primary tubes, TIG-welded seams, and 3/8-inch-thick laser-cut flanges. They are designed to improve exhaust flow, increase horsepower, and withstand high-temperature, high-demand environments.
The passenger-side flange features a beveled ball-and-socket connection designed to mate with the factory Y-pipe using a donut-style gasket. Before purchasing, verify that your vehicle uses the specified beveled Y-pipe connection, as some variations may have a flat flange.
