HKS developed an extension pipe without the catalytic converter and a frontpipe that will connect it to a catback exhaust system. The K20C engine was designed for use in a normal road car and features a catalytic converter, removing this converter eliminates its restricting effects which significantly increases the engine horsepower.


  • Removing catalytic converter results in a more linear boost and throttle response
  • Uses 3 inch pipes, compatible with HKS catback exhausts
  • A perfect addition to intake, intercooler and other HKS products for future ECU tuning and boostup
  • Decreases secondary exhaust gas pressure from turbine and reduces exhaust restriction
