Cat Converter
A few years ago we helped a friend move across country and she rented a very large UHaul truck that was on a F650 chassis. I did see that obviously this company was having the same problem because they actually had a full protective cage welded around the cat. Might not stop someone with a really good metal saw but would definitely make them think about going on to another victim. Engraving, etc., is not going to stop them in my opinion.
