Installation Notes

Use the listed vehicle fitment before ordering. For the 2008-2012 Chevrolet Malibu, 2007-2009 Pontiac G6, and 2007-2009 Saturn Aura, the notes specify federal and California emission model coverage, but this converter is not legal for sale or use in California and other CARB-compliant states. It is legal in New York and Maine on EPA federal-emission-equipped vehicles only. An exhaust gasket is recommended, and additional parts 31610 and 31337 are listed as needed to complete installation. Verify flange style, inlet and outlet diameter, and front converter position before installation.
