I'm trying to help a relative who lives in California find a source for a catalytic converter for a 2006 Prius. The need to replace the catalytic converter was indicated by a state-required engine smog test. We'd like to avoid having to buy from a Toyota dealership since their price would probably be much higher than aftermarket sources. I can find many sources of catalytic converter for the vehicle but, so far, they all say they are not legal in California. Does anybody know of non-dealership sources for catalytic converter that meet California standards?
