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.

  • Formulated to withstand extreme temperatures (stability rating is 1700° F vs 1300° 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, such as when using superchargers and/or nitrou
  • 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, the surface appearance is more consistent than that of a silver cerami
  • Works with factory power steering and power brakes
