Also, anyone know why most of the online sellers won't ship or sell to California? Does California have special rules regarding the catalytic conv?

Because there are 3 tiers of cats....................
Top tier = OEM and over 90% efficient,this includes cats sold aftermarket under the OEM cat manufacture name brand also(both most expensive cats) and are 50 state legal.Will have a CARB certified label.
Middle tier = Mid price range cats,48 state legal and only 66% efficient.
Bottom tier = Those cheap cats(all of the universal fit cats) and are only 33% efficient,in most cases will not pass emissions.
The bottom 2 can not be sold in CA or NY by state laws.
