Why We Choose HJS Catalytic Converters:  HJS German imported catalytic converters are made from some of the highest grade materials you can find in a catalytic converter. This yields high performance gains and longevity so it wont deteriorate over time like lower grade catalytic converters. These catalytic converters flow up to 93-95% of a straight pipe in most applications. The benefit is that you get the "straight pipe sound" while still being able to provide enough emissions scrubbing to prevent a check engine light.    If you'd like to learn more, watch our video about HJS catalytic converters. DISCLAIMER: This product removes the OEM catalytic converters from the vehicle, and as such, is strictly intended for closed track events and off-road use only. This product is or contains a Racing Cat Bypass Pipe, which will give you check engine lights on OBD2 cars. Racing Cat Bypass Pipes are solely intended for track and race cars as they are NOT California Air Resources Board Certified and not EPA certified.
