Most of the headers available today on the market come non-coated or sporting a black coating that tends to burn off quickly after short use. With most of the headers today designed to be wrapped or painted by the customer, Hedman Hedders has eliminated all the hassle and annoyance. The Hedman Hedders GMC Sierra Street Series HTC Coated Headers are treated with Hedman's famous HTC ceramic coating for a tank-like, and long-lasting lifespan. This innovative aerospace, metallic-ceramic composition is some of the highest-quality thermal coating available on the market. It improves heat insulation, providing thermal protection up to 1,300 degrees. HTC coating is bonded to the headers with a strength factor that exceeds 10,000 psi (pounds per square inch), so it won't chip, peel, or discolor. It's easy to clean and is guaranteed against rust-through for a longer lifespan and durability even after years of continuous use.

Each GMC Sierra Header set comes with headers for both side of the engine, and improves airflow and backpressure to promote improved throttle response, greater low-end torque power, and better fuel economy. Built using high-quality mild steel materials depending on application, mounting hardware and installation instructions are included. These application specific exhaust manifold sets are built for a perfect fit and feature a limited lifetime manufacturer warranty against defects and a 5 year manufacturer warranty on the HTC finish.
