Catalytic converters

If you purchase an OEM cat from your dealership does it have a warranty of 8 years? The dealership told me it was only for a year…confused by mechanics as usual. Who out there can give me some truthful information?!

Replacement parts do not have to be warrantied like the original emissions control system did…Very few people buy OEM cats…

never heard of a part being warranted for 8 years unless its a new car itself. and as of oem stuff some stuff is better aftermarket
