If you have a front 02 and a rear 02 there is supposed to be a difference in the reading with a cat installed. This is what i think happened, your gutted cat didn't allow for a change in the reading, check engine light on.
when you created a leak, there was a difference in the reading no check engine light. Maybe loooong stretch?
