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.
