I had to replace my right cat a few months ago and ran into this same issue. I would send a message to the seller to confirm is is CA Carb compliant. It is a universal application so you would have to get it welded and fitted for the custom mod.
Other than the universal application cats you will probably have to go with used cats off another M35 or G35 from ebay. I had to use a G35 cat since I couldn't find a decent priced cat I wanted to pay for. But haven't had any issues since.
