Review DOUGS HEADERS Chevrolet Uncoated Raw Steel Oval Port Shorty fits PATRIOT 1955-57

Doug's Headers TF700402 is a superior exhaust headers solution for 1955-57 Chevrolet models equipped with a 265-400 cubic inch small-block engine. This header set, manufactured from raw, uncoated steel, showcases a shorty design, aptly named the "Patriot." Uncoated headers offer the advantage of increased thermal conductivity, which aids in faster exhaust gas scavenging and enhanced engine performance. The "Patriot" shorty design reduces the overall exhaust length, allowing for a lower and more tucked exhaust system appearance, and releasing the engine's power more efficiently. The Doug's Headers TF700402 set makes use of a 1 5/8" primary piping diameter, seamlessly connecting to the engine's exhaust ports via 180-degreeange flanges. The collectors merge into a 2 1/2" crossover pipe, ultimately connecting to a dual 2 1/2" exhaust system. This header set is a crucial component for providing improved gas flow, reducing backpressure, and ultimately increasing horsepower and torque in your classic Chevrolet engine.
