Hey guys, posting this for my uncle who has a 04 Pathfinder LS. His cel came on about a month ago and after getting code pulled, turns out both his cat converters have failed. Sounded kind of weird to me that both would fail at same time but the car does have almost 130k miles. Obviously he got quoted an ridiculous amount of money for replacements from dealership ($700+ i believe) so I'm looking to see if anyone is parting out a pathfinder or anything like that. Are my chances bleak to find a used converter? or should I tell him to buy aftermarket which might be cheaper than oem?
