Specifications

Hooker Competition headers are designed for stock or mildly modified engines for the value-conscious buyer. Made from durable 16-gauge steel, Competition headers feature 5/16 in. thick flanges that are heavy enough to maintain header integrity, yet pliable enough to seal each exhaust port. Unless otherwise noted, these headers are designed to fit the vehicle as it came from the manufacturer. This includes components like cylinder heads, chassis, steering, motor mounts, body mounts and bushings, etc. If your vehicle is using aftermarket components, parts from other applications, or custom altered parts, then it is the installer's responsibility to verify fitment.
