I want everybody in here to know that there's a federal 80K mile cat warranty. Not dealer warranty, federal warranty. If your cat goes bad before 80K miles, by law the dealer has to replace it. Pass this info on to everyone you know. For further info: http://www.epa.gov/oms/consumer/warr95fs.txt

 

Its mandated that the auto companies have to cover it, yes... But it all depends on the year, model, and weight of the vehicle.
