  JBA long tube headers are the number one choice for maximum performance gains and high RPMefficiency. These long tube designs are dyno and race proven to deliver the greatest possible increase inhorsepower and torque throughout the RPM range. All JBA long tube headers feature large mandrel-bentstainless steel primary tubes, oversized exhaust ports, extra thick 3/8' one piece flanges, and patentedJBA Firecone* merged collectors for smooth flow. Each system is designed to give the maximum amountof ground clearance possible so lowered cars do not drag the collectors. Each system includes highquality hardware and thorough instructions for a professional no-leak installation.
  *Standard on 4-1 long tube V8 applications. Not available on Tri-Y headers.
