Well in FL its a $500 fine and a 1st or 2nd degree misdemeanor charge. Plus, mechanics can be fined $2,500 for removing your cat illegally, so u might have a hard time finding a shop that will do it for ya. So if California is more strict....i personally wouldnt risk it just to gain a few horses. Just buy a performance hi-flow CAT if you want the OEM one gone.
