Dang OB. I just dropped $2k for a used engine with only 60k miles on it. Surely new cats aren't that much are they? I hate to see a really nice well cared for X like yours go to someone that doesn't appreciate it. If you really do get rid of it, please consider selling it to an enthusiast. If you weren't 3000 miles away and I hadn't just bought that engine I'd consider buying and putting new cats on it.

Possible alternative, given its age you could get away with hollowing out the cats or putting headers on it? CAT delete?
