This exclusive proprietary black ceramic coating offers the nostalgic look of the past as well as the aggressive look of a modern high-tech build. It also offers a more refined texture and appearance than is possible from painted finishes. With a satin sheen it has a unique look of its own and in addition to providing a more menacing look it also provides all the corrosion resistance of traditional silver ceramic. The Darkside coating also provides improved thermal resistance as compared to traditional silver ceramic (1700° F vs. 1300° F) making it highly recommended for supercharged or nitrous applications as well as for reduced under-hood temperatures.

Features:

  • Formulated to withstand extreme temperatures (stability rating is 1700° F vs 1300º F on silver ceramic) without discoloration and maintains excellent adhesion even after repeated thermal cycling
  • Provides a higher heat tolerance threshold than available from silver ceramics (ours or any of our competitor’s) and is therefore recommended for any applications producing elevated exhaust gas temperatures
  • High-efficiency thermal properties limit heat migration through the header assembly, which in turn lowers under-hood temperatures for more performance
  • Increased corrosion protection ensures long service life and maintained appearance of investment
  • Provides 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 after its application
  • Works with factory power steering, power brakes and air conditioning

Installation Notes:

Reducers not included. Will not fit motors equipped with air injection pump without modification. Hooker Headers for MOPAR 383-440 engines will bolt to the popular B-S heads. However, because the exhaust port centerline on these heads is 5/8" higher and 3/8" out from the engine centerline compared to stock heads. Some header modifications will be required for installation. Custom header applications will be required for the B-1 heads because of angled spark plug locations. Long-tube headers do not include reducers. Do not use header wraps; they can cause header tube cracking from excessive heat or rust from moisture build-up and void the warranty. Breaking in an engine with ceramic-coated headers can damage the coating and void the warranty. Use cast-iron exhaust manifolds or old headers during engine break-in to prevent coating damage. Ceramic-coated headers require several heat cycles to fully cure before withstanding extreme heat. For additional information about ceramic-coated exhaust products, call Hooker Technical Service at 270-781-9741.
