      Unique Header Design. The Flowtech HDR 73-74 CHEVY/GMC TRK 2WD Afterburner Headers feature an innovative turbo chamber design that enhances exhaust gas flow and reduces turbulence. This results in improved horsepower and torque, broadening the power curve for more usable performance across the RPM range.

      Construction and Appearance. Crafted from durable mild steel, these headers feature 1.625-inch primary tubes and a large 3-inch secondary collector to minimize back pressure. They are finished with a black satin paint that offers protection against corrosion and provides a clean, performance-oriented appearance.

      Installation. Installation is straightforward with all necessary hardware and premium gaskets included, requiring no drilling. Designed as a direct fit for the specified vehicles, these headers offer a hassle-free upgrade to the exhaust system.

      Application. Specifically designed for 1973-1974 Chevy and GMC 2WD pickups and Blazer/Jimmy/Suburban models equipped with 283-400 small block V8 engines. This product is intended for racing use only and is not legal for emission-controlled vehicles.
