Used, original, Toyota (33737 Futaba) catalytic converter, removed from my Toyota Prius 2017 (62 000 miles), as the heating exchanger had to be replaced and that included the catalytic converter. The item is used, it may have scratches, as seen in the photos. It is fully functional. I can provide evidence that it was removed by Toyota (to fit new heat exchanger and catalyctic converter). Please ensure it fits your car before you buy it (based on the item code), as returns are not accepted. This only fits the 4th generation Toyota Prius.
