It is illegal to advertise or sell used catalytic converters in the state of CA. The California Air Resources Board (CARB) is a rouge agency with no accountability to the people of the state who pay for their existence. They pass laws without consideration for any burden it will place on the people and since they are not accountable to us, we cannot directly push them to change things. Look at the plague that is the theft of catalytic converters, CARB is doing absolutely NOTHING to offer avenues for relief to the people to use secondary market parts or EPA certified parts which are significantly less.
