Info

Hooker Competition headers offer the best value in the high performance header market. Designed for the value-conscious buyer who is running either a "stock" or "mildly-modified" engine, Hooker Competition headers offer premium features at a very competitive price. Made of durable 16 gauge mild steel tubing, the Hooker Competition header design utilizes a long transition collector to reduce back pressure and increase exhaust flow. A perfect sealing surface is assured with the 5/16" machined flanges, with welded O-ring seals. Experience has proven that this flange size is ideal to maintain header integrity and be pliable enough to seal each exhaust port. Tubing is mandrel-bent to maintain metal strength and provide consistent tube diameter at radii to maximize performance. Hooker Competition headers have a standard finish that features a heat-cured, high-heat-resistant paint. Optionally, the famous Hooker Ceramic Thermal Barrier Coating is available. 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.

  • 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
  • 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 nitrou
  • 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
  • Works with factory power steering and power brakes

Notes

Will not fit angle plug cylinder heads. Tube number 1 and 6 has a factory dent to allow plug clearance. Will work with factory air conditioning with the use of Hooker brackets. The paint applied to these headers is a temporary coating only and is designed to burn off during use. High temperature paint or other high temperature coatings are recommended.
