Right. That. I think I even commented on that somewhere.

Well, of course the cat manufacturer is pointing the blame elsewhere, but they are using big words and pretty pictures, so they must be correct. Their example of an overheated catalytic converter:


Mine:


They do not show the inside, though. Mine is not melted at all, although a chunk of carbon came out of the bung hole. I have an "Atomic Beam" flashlight and cannot see anything in there, but I can see perfectly from one end to the other.

Excessive rich fuel conditions and exhaust leaks ahead of the converter are prime examples. They result in higher than normal temperatures that can cause matting erosion and burn away or melt converter coatings. If temperatures are high enough, the ceramic substrate itself will melt and clog.
Look upstream for the culprit in a converter failure - Eastern Manufacturing

I called Mom's shop because I feel they have always been honest and good, but they were busy, so she said she would call me back with a quote. They use Magnaflow and Imco.

Imco? Great! I never heard of them!

Doesn't Scotland do warranties?
