Berk Technology’s Honda Civic High Flow Catalytic Converter (HFC) is a direct bolt-on replacement to the factory catalytic converter. Our HFC features 3″ stainless steel tubing and a very smooth transition down to 70mm at the catback flange for compatibility with stock and aftermarket exhaust systems. This new high flow cat also features a J-Bend extended O2 sensor bung to help eliminate the dreaded check engine light and a high quality US made metallic catalytic converter element for superb heat resistance and performance.
This new high flow catalytic converter is already seeing horsepower gains in the Honda Civic Si community throughout the entire power band with peak gains of 7 wheel horsepower and 18 ft-lb of torque!
As of January 1st, 2009, performance high flow cats are intended for off-road use only in the state of California. Made in the USA and is EPA approved.
