PART #: 2455-3HKR

UPC #: 700414007229

Emission Control Number 3

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.
Fits 396–502 CID Big Block Chevy Engines; 2.0" Primary Tube; Port Shape: Same As Port

Installation Notes
This header will not fit with a manual transmission on the Monte Carlo or late passenger/wagon models and will also not fit on Camaros with a column shift.

Factory style big block frame stands and motor mounts must be used to ensure proper engine locations and header fit. Aftermarket solid and urethane mounts, worn or incorrect mounts will cause header fitment issues.

This header was designed around the factory big block motor with factory heads. Tall deck big blocks, raised port heads or non-stock plug locations may cause header fitment issues that require modification to fit.

This header will not fit with close ratios steering boxes or rack conversions.

WARNING! Breaking in an engine with ceramic-coated Headers WILL result in damage to the coating and will VOID all warranties. Ceramic-coated Headers require several heat cycles to fully cure before they will withstand extreme heat. Hooker® recommends using cast iron exhaust manifolds or old Headers to break in new eng

  • 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, such as when using superchargers and/or nitrous oxide systems
  • 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 ceramic coated header. Be different and go black!
