Detailed Description
Exhaust Header; Set;
The Darkside coating also provides improved thermal resistance as compared to traditional silver ceramic (1700 degree F vs. 1300 degree F) making it highly recommended for supercharged or nitrous applications as well as for reduced under-hood temperatures
- 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
- 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
- Formulated to withstand extreme temperatures (stability rating is 1700 degree F vs 1300 degree F on silver ceramic) without discoloration and maintains excellent adhesion even after repeated thermal cycling
- Works with factory power steering and power brakes
Brand Information
In 1962 Gary Hooker designed a header for his 409 Chevrolet and discovered a demand for this header from other racers in the area. It wasn't long before Gary hired employees and was operating Hooker Headers out of a building in South Ontario, CA. The Hooker philosophy was simple - make real, useable power by balancing the intake and exhaust pressure waves. This efficiently expelled all the burnt gases while drawing in the maximum fresh charge of fuel and air. The Hooker team sometimes spent twice as much time developing a header to find 10% better performance. Hooker dominated the drag race scene in the late '60s and throughout the '70s with nearly all NHRA(R) Pro Stock (Super Stock) racers winning with Hooker Headers. Famed racers such as Bill "Grumpy" Jenkins, Bob Glidden and Sox & Martin were regulars in Hooker PR. Hooker straight-thru glass pack mufflers were also launched in the early '70s, known as the "Hookermuffler". This branching led to more "non-race" header and exhaust applications for trucks, vans, motor homes, and economy cars. Hooker had headers for nearly anyone that could benefit from the mileage and performance improvements seen from un-corking your exhaust. Hooker also became famous for engine swap headers. In the early '90s Hooker developed its Metallic Ceramic Thermal Barrier Coating as an optional finish on its headers. The heat displacement properties and additional life it added to headers make it one of Hooker's most popular features still today. The '90s also saw the development of the Aerochamber Muffler; the most advanced muffler of its time. Hooker still holds tight to the claim of the winningest header in drag racing history. Hooker still leads the way in design and technology with products like engine swap headers for putting a late model LS engine into early iron. The famous Hooker heart logo is among the most recognized in the performance aftermarket, symbolizing unmatched performance and quality.
