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.
Some parts are not legal for use in California or other states with similar laws/regulations
