This definitely wont work in CA. You can't even replace your cat with just any cat in CA. There are cats you can buy for 49 states, and there are CA CARB compliant ones. They're stamped with a serial number, so even if you pass emissions tests, the smog shop will need to verify that your cat has that stamp. It's a headache.
