55-57 Chevy Headers

The HOOKER 55-57 Chevy Headers deliver competition-grade exhaust scavenging for small-block Chevrolet engines in first-generation fullsize cars. With 1.625-inch primary tubes converging into a 3-inch collector, this pair of headers is engineered to maximize exhaust velocity and reduce backpressure—critical factors in extracting horsepower from classic Chevy powerplants. The metallic ceramic coating protects against thermal stress and corrosion while maintaining the authentic appearance expected in restoration and performance builds.

Constructed from steel and finished with a durable ceramic coating, these headers are designed for sustained high-temperature operation. The 1.625-inch primary diameter is sized specifically for small-block Chevy displacement, optimizing scavenging efficiency across the RPM band typical of street and competition applications. Installation is streamlined with gaskets and hardware included—no hunting for fitment-specific fasteners. The compact collector design (3-inch diameter) allows integration with single or dual exhaust systems downstream, giving builders flexibility in final exhaust configuration.

This header set is purpose-built for 1955–1957 Chevrolet fullsize vehicles running small-block engines, whether as an upgrade from restrictive cast-iron manifolds or as part of a comprehensive performance package. Competition builders and restoration enthusiasts choose headers like these to improve throttle response, increase peak power output, and achieve a more aggressive exhaust note. The pair configuration covers both banks, eliminating any guesswork about left-right fitment in original engine bay layouts.
