If you're looking for headers designed for maximum street performance, look no further than Hooker Competition headers. Hooker Competition headers are designed for stock or mildly modified engines for the value-conscious buyer. Made from durable 16-gauge steel, Hooker 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.

Footnotes: 4 - Exhaust systems can also be fabricated using either Hooker Super Competition mufflers, Aero Chamber mufflers, Maximum Flow mufflers, Super Competition turbo mufflers, Competition turbo mufflers, or header-type Hooker mufflers.
10 - Will not fit motors equipped with air injection pump without modification.
200 - Hooker headers for Mopar 383-440 engines will bolt on the popular aftermarket B-S heads. However, because the exhaust port centerline on these heads is 5/8 in. higher and 3/8 in. out from the engine centerline compared to stock heads, some header modifications will be required for installation. Custom header applications will be required to fit the B-1 heads because of the angled spark plug location.
