Description

With Hooker Super Competition headers, the objective has always been to make the maximum horsepower possible and put it at the optimum point in the power curve. Hooker Super Competition headers feature tuned primary tubes to create optimum pressure between the intake and exhaust systems. Hooker Super Competition headers include premium exhaust gaskets and new mounting bolts. 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.
