Does not fit with angel plug or raised port heads. 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.

Features:

  • Tuned-length primary tubes for street performance
  • Mandrel-bent tubing for smooth exhaust flow
  • Light weight & sturdy 16 gauge tubing
  • Long transition collector for decreased back pressure
  • 5/16” machined flanges for a perfect seal
  • Industry’s best welds for durability
  • Designed for easy, trouble-free fit
  • All necessary hardware included for a complete installation
  • Works with factory power steering, power brakes and air conditioning

Instructions

Instructions for Part# 2452-1HKR


***Breaking in an engine with ceramic coated headers WILL result in damage to the coating and will VOID all warranties. Hooker recommends using cast iron exhaust manifolds or old headers during your engine break-in period to avoid damaging your coated damage. Please call Hooker tech service at 270-781-9741 for additional information regarding ceramic coated exhaust products. The use of header wraps can cause the header tubes to crack or rust due to excessive heat and moisture build-up. Hooker does not recommend the use of header wraps as this will void the warranty. Hooker long tube headers do not come with header reducers.
