Key Features

  • The significant changes in exhaust flow affect air fuel ratios and require ECM recalibration to achieve optimal power output and safe operation.
  • Catted versions with Kooks GREEN or high flow catalytic converters comply with federal emissions standards but are not CARB certified for California.
  • Catted connection pipe versions include replacement high flow cats.
  • Most Kooks connection pipe kits are designed to mate with the factory cat back exhaust inlet diameter.
  • Long tube headers replace the factory exhaust manifolds and generally require removal of the factory catalytic converters.
  • Tight engine bay clearances on some platforms can increase install time.

About Kooks Headers

Kooks manufactures performance exhaust components in the United States, including headers, connection pipes, catalytic-converter assemblies, cat-back systems, mufflers, flanges, and installation hardware. Exact part-number verification is essential because similar-looking components can use different engine, chassis, emissions, and connection configurations.
