FWIW, here are my numbers from the two times I have smogged the car (it passed both times). Stock cats. Done at different shops, so I don't know if a trend can be established, but it sure looks like it's getting worse. Good thing I'm getting the DACH Sport Cats!

Thanks for the advice! Yes, I am considering the DACH. I also located an oem for the same price. Too bad the wait for the DACH is going to be a while since there are now a couple of builds in queue! Chris's product looks really good to me! No chipping yet, so I assume I had a meltdown of the cat for sure. Will find out soon .
