Precious metals and large substrate minimize pollutants in your exhaust Quality inspected and tested - high heat resistance, low emissions and sounds levels Special design for maximum flow increases the power and performance of your engine Legal Disclaimer This product is not legal for sale or use in California, Colorado, New York and Maine due to state emissions regulations. 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. Any modifications of any kind will void all warranty coverage for this item. 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 you replaced the converter. Catalytic converters turn airborne pollutants into less harmful gasses and improve the efficiency of your vehicle. A compromised catalytic converter causes your engine to misfire, lowering your vehicles fuel efficiency and causing it to emit harmful pollutants.
