The Coated Header – 99-07 GM P/U 4.8/5.3/6.0L from Hedman is a direct-fit performance exhaust header designed specifically for 1999–2007 GM full-size pickup trucks and SUVs equipped with LS-series V8 engines. This product is ideal for truck owners and mechanics looking to enhance exhaust flow and performance. It replaces the factory restrictive manifold, allowing for improved horsepower and torque gains.
Constructed from mandrel-bent steel tubing with a primary tube diameter of 1.625 inches, the Coated Header maximizes exhaust gas velocity while minimizing turbulence. The metallic ceramic coating provides resistance to thermal degradation, reduces radiant heat, and protects against corrosion and oxidation, ensuring durability in harsh conditions. This design is critical for LS-series engines, where efficient cylinder scavenging directly impacts power output.
Mechanics and truck enthusiasts working with 4.8L, 5.3L, or 6.0L LS engines will find this header suitable for naturally aspirated builds or as a foundational upgrade before adding turbo or supercharger systems. The stock collector flange ensures compatibility with OEM or aftermarket exhaust systems, while included gaskets and hardware simplify installation. This pair configuration covers both banks of the V8, providing balanced performance.
