Our high flow catalytic converter is designed to meet even exceed OE quality and performance standards. Made from HD-Stainless steel, high flow design to provide more oxygen for an increase in power and performance, fully tested under the extreme conditions for heat resistance and service life. High Flow Cats Increase Power The problem with regular catalytic converters is that they don’t always allow the gasses to pass through as efficiently as possible. High flow catalytic converters allow for the more efficient flow of exhaust gasses, removing restrictions that can impede performance. If the original OE converter does not match your engine power, a high flow cat might be a great choice.

But before replacing a catalytic converter, please make sure your O2 sensors still work well. Faulty sensors can cause damage to spark plugs, catalytic converters and damage your fuel economy. Installation Guide:Raise the vehicle and secure it on jack stands.Identify the catalytic converter on the underside of the vehicle.Remove the oxygen sensors.Spray penetrating oil on the exhaust flange hardware and flanges, then remove the Old Catalytic Converter.Install new catalytic converter, direct bolts to existing exhaust system – Do not forget to install gaskets to prevent exhaust leaks.
