BMW M5 Catalytic Converter - Select Year

Direct Fit Catalytic Converter - New CARB regulations that went into effect on January 1, 2009 now require
all exhaust catalyst devices that are sold in California regardless of
model year must meet the tougher OBD II emission standards that were
introduced in the 1996 model year. Until further notice, this catalytic
converter should not be used on vehicles registered in California. -
