Caution:
Converters are designed to last the life of a vehicle. If your converter needs to be replaced it may be due to an emissions error/problem in your engine tuning. Converters that overheat due to engine problems may turn blue or bronze. These problems must be corrected BEFORE installation of a new converter
Warranty is voided if catalytic converter substrate is melted or broken; this is due to an issue with the car itself and not the catalytic converter
Due to its size and shape it may encounter cosmetic flaws during its stocking and shipping process. The powder coating finish is designed to add shelf life by minimizing surface scratches which may deteriorate over time due to temperatures reached once in use
Products damaged as a result of abuse, misuse, improper repair, improper installation, alteration or modification will not be covered by the warranty
O2 sensors must be replaced when you replace the converter or warranty will be void. We have determined that failure of either the front O2 sensor (the front wide-band sensor), also known as an Air-Fuel Ratio Sensor or the read downstream sensor, can trigger a false P0420 code. Both sensors should be replaced with your replaced the converter
