I was browsing a parts catalog (not one of the usual list vendors) and when I looked
up the catalytic converter for a '90 Vanagon, there was this note on the page:
    "With oxygen sensor hole. 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."

Anyone in California subject to CARB rules care to comment?

Just wondering.
