Description

Switch to the Darkside! Hooker Competition Darkside ceramic coated headers feature an exclusive proprietary black ceramic coating that offers a more refined texture and better appearance. They are manufactured from durable 16-gauge steel and have 5/16 in. thick flanges that are heavy enough to maintain header integrity, yet pliable enough to seal each exhaust port. These headers provide improved thermal resistance up to 1,700 degrees F, limiting heat migration through the header and reducing underhood temperatures. Unless otherwise noted, they 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.

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.
