The large, mandrel bent, tuned length, primary tubes are custom engineered to give you more velocity, exhaust gas scavenging and high RPM efficiency resulting in more high end power than what you can achieve with a set of street performance headers.

  • Tuned length mandrel-bent primary tubes offer maximum exhaust flow, and scavenging to make you more power.
  • Long transition collectors for decreased back pressure improving high end power.
  • Strong light weight 18 gauge tubing helps you reduce the weight to increase performance.
  • Optimal design 5/16'' thick header flanges provide a combination of clamping force and rigidity for perfect seal.
  • Designed for optimal high RPM performance.
  • Includes gaskets and bolts.
  • Reducers are not included.
