J's Racing has designed a stainless (SUS304) header combined with a special thermal wrap. The thermal wrap increases exhaust temperatures and velocity, which contributes to higher horsepower and lower engine bay temperature.
  • Structure: 4 (50) - 2 (50) - 1 (60)
  • Weight: 5.6kg (vs stock 10.5kg)
This header significantly increases the horsepower at all engine rev ranges. It is made of light SUS304 with 1.2mm to 1.5mm thickness. Each is beautifully handmade by professional craftsmen with amazing detail. It has taken almost 2 years of research & development to perfect this header that has proven performance advantages from countless dyno testing. J's Racing header will maximize the potential of the F20C and F22C engines. J's Racing has also added an A/F ratio sensor fitting hole.
