      Description

      Performance Exhaust System. The Hooker BlackHeart Header Back Exhaust with No Muffler is designed to optimize exhaust flow by reducing backpressure, enhancing engine efficiency and overall performance. This system is intended exclusively for competitive racing environments to deliver improved horsepower and throttle response by efficiently channeling exhaust gases away from the engine.

      Construction and Appearance. Constructed from durable 16-gauge aluminized steel tubing, this exhaust system features mandrel-bent bends that maintain consistent tubing diameter and prevent flow restrictions. The aluminized finish offers corrosion resistance, making the system robust enough for demanding racing conditions. The pipe-only design omits mufflers for unrestricted exhaust flow.

      Installation. Installation is straightforward with included hardware and instructions. The system is designed as a precise bolt-on fit to work seamlessly with Hooker Competition headers, requiring no cutting or drilling for proper installation on compatible vehicles.

      Application. This header-back exhaust system fits 1973 and 1974 Chevrolet and GMC vehicles equipped with 307 or 350 cubic inch V8 engines. It is designated for racing use only and is not legal for street or emissions-controlled vehicles, ensuring compliance with racing regulations.
