Hooker Competition Long Tube Headers, 1964-1974 BBC, 2 In. Tube 3.5 In. Collector, Silver Ceramic 2455-1HKR

This exclusive proprietary Silver 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 ceramic coating also provides improved thermal resistance as compared to traditional silver ceramic (1700 deg F vs. 1300 deg F) making it highly recommended for supercharged or nitrous applications as well as for reduced under-hood temperatures.
Features:

• 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
• Increased corrosion protection ensures long service life and maintained appearance of investment
• High-efficiency thermal properties limit heat migration through the header assembly, which in turn lowers under-hood temperatures for more performance
• 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
• Formulated to withstand extreme temperatures (stability rating is 1700 deg F vs 1300 deg F on silver ceramic) without discoloration and maintains excellent adhesion even after repeated thermal cycling
• Works with factory power steering, power brakes and air conditioning

Hooker long tube headers do not come with header reducers. 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 engines to avoid coating damage. The use of header wraps can cause the header tubes to crack or rust due to excessive heat and moisture build-up. Flowtech does not recommend the use of header wraps as this will void the warranty.
