■Concept
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. HKS developed an extension pipe without the catalytic converter and a frontpipe that will connect it to a catback exhaust system.
■Features
- 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.

HKS Front Pipe / Downpipe
Diameter of pipe was studied and selected for each vehicle, engine performance and characteristics.Pipe is designed as straight as possible to reduce secondary exhaust gas pressure.Response of turbocharger is improved, and potential power of turbocharged vehicle comes out.
HKS
In October 1973, two talented and spirited young engineers had a vision; to design and build high performance engines and components that major OE manufacturers could not or would not produce. HKS pioneered the Japanese aftermarket performance industry by delivering a host of exciting new products, including the first commercially available electronic turbo timer and boost controller. Other early products included piggy-back fuel computers and sophisticated fuel management tools. Clearly HKS was Driving Performance trends for Japanese vehicles.
