Crazy: (OK back on topic...)
I have not had any problems with gutted pre-cats and a high flow main cat for 45K + miles. If I went through the whole pre-cat problem scenario again, I would have gutted them earlier. (Before clogging up a 3rd main cat) I don't think it's cost effective to repair these out of warranty as you will not get the money back in resale value, lower cost operation, better reliability, or even better sleep. (Unless you ARE Al Gore. Oh no, can't go there again...) You will, however get a more gutsy duratec with one less cronic failure item to be concerned with.
