  • 1-7/8" diameter primary tubes for optimal exhaust velocity and power gains
  • Includes high-flow catalytic converters (catted connection pipes) for 50-state emissions compliance
  • Constructed from T304 aircraft-quality stainless steel for superior durability and corrosion resistance
  • Precision mandrel-bent tubing maintains consistent diameter for maximum flow
  • CNC machined flanges ensure leak-free sealing
  • Dyno and race-tested design proven to deliver maximum power output
  • Manufactured in the USA with strict quality control standards
  • Complete bolt-on kit for direct OEM replacement

Kooks Headers stands behind this product with a limited lifetime warranty to the original purchaser. This header system is ideal for enthusiasts seeking improved throttle response, increased horsepower, and an aggressive exhaust note while maintaining catalytic converters for street legality.
