Overview:

65-73 Mustang Long Tube 260-302 & 71-73 260-351W Raw 409

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

    Easy to use.
    Color: Grey, Size: 6 Panel
    These are easy to put together and to use. We have used them with all the panels. We have also used them broke down into 2 and 3 panels. They work well for blocking views. They don't block noise or help quiet the room being used, however. Only bad thing about them. We use them for our Auxiliary meetings.

    Easy to assemble. Still used for over a year 🙌🏾
    Color: White, Size: 6 Panel
    Everything is perfect! I would buy again in other colors and heights if I need additional separation in the basement.

    Cheap Garbage
    Color: Black, Size: 4 Panel
    This item is just cheap crap. Shoddily put together, shoddy materials, and looks cheap. If you’re just putting it in a space that you don’t really care that it’s cheap, then it might be fine for what you need. But don’t expect much.

    Keeps areas separated
    Color: Black, Size: 6 Panel
    Item arrived quickly. I use this to keep my cats out of a part of the cellar. Works great. They've figured out how to slip through side. I made a panel that covers those spots. Still the best item to keep area separate.
