If there is no condensation water sputtering or leaking out between the mating surfaces ( mine were till I used Remflex ) at the cold start, then there is no leak.

Interesting. I got a CEL when I went out for lunch, so I'll pull the code when I head home and if it's rear O2 related I'd say I have a leak. I did double check to make sure Shiv disabled the CEL for cat efficiency, so it's not due to the lack of cat.
I assume you've had the remflex gasket in for a while? I saw some old posts on Nasioc about them failing (but that was on turbo cars, so who knows)
