JBA long tube headers are the number one choice for maximum performance gains and high RPM efficiency. 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 patented 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. Each system includes high quality hardware and thorough instructions for a professional no-leak installation. *Standard on 4-1 long tube V8 applications.
