Overview:

99-04 Mustang Long Tube 4.6L 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.

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 idea poor construction
    Color: Large size (7.9"), Color: Large size (7.9")
    Great for a dog that likes tug and fetch but the seams are not strong so it ripped fast not from tug but my dogs teeth. I sewed it once since we loved playing with it but it didnt last. Other seams opened. The seams opened in the ball part not by the handles. Less seams and stronger ones would make it 5 star. Im trying a different brand.

    Keeps her busy!
    Color: Medium size (5.9")
    Our Molly loves this. Only thing is that it is a little too big for our Maltipoo, but she still tries to keep up with it.

    So far my dog hasn’t destroyed it! And it’s been a month. So I call that a win. Plus he loves it.
