If I have a CA emissions compliant vehicle and I need to replace the Catalytic converter on my vehicle. Does it have to be a CA emission compliant converter for a replacement if I do not live in CA nor have any plans of ever registering the car in CA.

I know there is a difference in the internal make up of the catilytic convertors (CA compliant and non-CA Compliant) with the metals used.

My question is more to all the sensors (O2, Mass Airflow, and others). If I replace the Converter in this case with a Non Compliant CA converter will it throw a engine code or cause the vehicle to not operate correctly. I do not know if the engine computer system/sensors also operate differently on a CA compliant vehicle vs. a non compliant vehicle.

for reference: it is a 2001 Toyota Camry LE V6 3.0L Automatic Trans, with 150k on it that is my kid's car.
