An exhaust gasket is recommended, and additional parts 31643 and 31369 are listed as needed to complete installation. This converter is not CARB certified and is not legal for sale or use in California and other CARB-compliant states; it is legal in New York and Maine only on EPA federal-emission-equipped vehicles. Confirm local aftermarket converter regulations before installation.
