    The Hooker "Darksides" Black Ceramic Coated Headers offer the nostalgic, aggressive look of black with a more refined texture and appearance than is possible from any painted finish. The satin sheen provided by this coating is truly striking and sure to please. In addition to providing a more menacing look, which makes a fresh styling statement, Hooker's new Darkside coating supplies all the corrosion resistance properties of the existing silver metallic ceramic coating plus improved thermal resistance to ensure peak performance and durability. Hooker Darksides provide a unique styling enhancement that is equally pleasing in either a nostalgic retro application or a modern hi-tech build. As this coating is not burnished (polished) after its application, the surface appearance is more consistent than that of a silver ceramic coated header. For street applications Hooker Headers Reducers are available separately.

    Be different and move over to the Darkside!
