Our high flow high-end catalytic converter kit features dual high flow genuine GESI catalytic converters. This kit is easily welded in place immediately after the exhaust manifold. These cats are recommended for high power RR Racing supercharged applications.

These cats work with vehicles up to 500 HP. Specially designed with a very high-flow level, they will not create engine codes in most vehicles, thus eliminating emissions-related "Check Engine" lights. Kooks Catalytic Converters work on naturally aspirated, turbo, and supercharged applications.

Warning: please check your local applicable laws, as removal or tampering with your cars emission/exhaust system may be illegal in some states. This system is not California CARB compliant and intended for motorsports race vehicles only.
