Rx8 Breezy

Ok so I live in California and I need a new catalytic converter. Unfortunately in january this new law was enforced making it extremely hard to buy one in California ( like near impossible I haven't found any so far) and just so happens I need to pass smog wich wont happen until i get a new catalytic converter. Has anyone found some site that will sell to California? I was thinking about buying from a family members address in az and then mailing it over but thats worst case. Also I'm looking for a highflow cat that will still pass smog
