From the Edmunds website:
There are many exceptions to registering non-CARB cars in CARB states. For example, here are the DMV rules and exemptions for registering non-CARB cars in California. Note that once a non-CARB vehicle has more than 7,500 miles, it is no longer considered new and can be registered in California, assuming it can pass the smog test.
