Overview:

67-70 Mustang Tri Y 390-428 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.

Each system is designed to give the maximum amount of ground clearance possible, so lowered cars do not drag the collectors.
