Will this fit my car?
The product is compatible with Toyota Prius, and there is a compatibility list as a guide on the page of Vehicle Fitment for you. If you are still uncertain, please contact with the customer service.

Come with the sensors?
This catalytic converter packaging does NOT include the O₂ sensor, but the cat has a O₂ sensor plug.

Is it approved by California?
Sorry, no. It is prohibited from sale in California, Colorado, Maine, and New York due to State emissions regulations.

Welded or flanged?
This type requires both installation methods, the inlet uses the 2-bolt welded flange connection, while the outlet adopts the pipe connection via welding.

What to do if check engine light comes on?
Ensure that the gas and oil caps are on tight and that the oil dipstick is seated correctly. If the light remains on, it could be triggered by a faulty oxygen sensor, wrong installation of catalytic converter, bad spark plugs, malfunctioning thermostat or bad mass air flow sensor. If none of the above is true, please contact with the customer service ASAP.
