CARB Compliant - Aftermarket Pre-Cat & Cat ?

Been trying to look for some CARB-Compliant (CA legal) aftermarket precats & cats for a 2002 Pro5.

The CA Catalytic Converter search tool link doesn't have the 2002 Pro5 listed. Can I use a 2003 precat & cat instead?

Also, any other (legal) suggestions would help (would love to do the prefouler or go headers, but that's not an option). Thanks in advance.
 
I would be carefull going aftermarket because if its not a decent cat then it might not throw a code. But sometimes they wont set the rediness test and you still wont pass for a sticker
