The catalytic converter uses a ceramic substrate to convert carbon monoxide, unburned hydrocarbons, and oxides of nitrogen in the exhaust into less harmful gases. If a clogged, contaminated, or failed converter is behind a failed emissions test, a P0420/P0430 code, a rattling honeycomb, or a sulfur smell, this direct-fit unit replaces it. It measures 20.5 inches in overall length and is made in the United States. As a Federal / EPA converter it is not CARB-certified and is not legal for sale or installation on vehicles registered in California, Colorado, Maine, New York, Washington, or other states requiring CARB-compliant converters; confirm your state's requirements before ordering.
