I was wondering is the gen3 prius cat and 2017 prius prime the same? Im asking because the heat exchanger is broken and im leaking coolant out of the exhaust and my friend have a gen3 cat. another question do i have to buy the whole center piece or i can just buy the green over lay?
They're identical. To confirm do some comparison shopping for catalytic converters for both 'em and see if there's any mention of them being different vs. compatible.
