Overview:

67-70 Mustang Tri Y 390-428 Silver Ctd

JBA long tube headers are the number one choice for maximum performance gains and high RPM efficiency. Available in 409 or 304 Series Stainless Steel. These long tube designs are dyno and race proven to deliver the greatest possible increase in horsepower and torque throughout the RPM range. All JBA long tube headers feature large mandrel-bent stainless steel primary tubes, oversized exhaust ports, extra thick 3/8 one-piece flanges, and proprietary JBA Firecone® merged collectors for smooth flow. Each system is designed to give the maximum amount of ground clearance possible, so lowered cars do not drag the collectors.

Features:

  • 3/8" thick CNC laser-cut flanges
  • Patented JBA Firecone® collector
  • O2 sensor provisions
  • Large diameter mandrel-bent steel tubes
  • Oversized exhaust ports

    Great socks
    Size: Large, Color: (002) Black / Black / Castlerock
    These are the only socks I’ll wear when working. They are so soft and comfortable. They are thick and heavy duty, and don’t wear fast. The fit snug and perfect. Good warm with a little compression for being on your feet all day.

    Good boot sock
    Size: Large, Color: (001) Black / Black / White
    Used these for over a year now. They cover your calf and really don’t move from that spot. Very comfortable.

    Okay But Not Worth The $$$
    Size: Large, Color: (390) Marine Od Green / Marine Od Green / Baroque Green
    Standard athletic sock. Cheaper ones are available through soooo many sources. UA seems to mean more expensive.
