JBA Performance Long Tube Headers – 36965S 1 3/4″ 304 Stainless (5.7L, 6.1L, 6.4L)

JBA competition-ready long tube headers are the number-one choice for maximum performance gains and high rpm efficiency. Their 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 in. one-piece flanges, and patented merged collectors for smooth flow. Each system is designed to give the maximum amount of ground clearance possible so that lowered cars do not drag the collectors. And, in addition, each JBA system includes high-quality hardware and thorough instructions to provide a professional, no-leak installation.
