Smog test failed. OBDII monitors not ready

Hey guys, I've been driving with high flow cats for about 2 weeks and just had a smog check done this morning and it failed some OBDII monitors. I'm not really surprised but I thought I would pass since I had no check engine lights. I figured if there were no check engine lights then the car should pass. I was wrong. 

Has anyone had this issue with high flow cats? The rear O2 sensors are mounted further down on the horizontal section before the x-pipe and not on the cats themselves like the OEM units. Is it possible the rear O2 sensors are not getting hot enough because they're not mounted on the cats where they can get hotter?

Also, I'm not sure why the evap system isn't ready. Is it because my fuel level was a little more than 1/4 full? I'm going to put my OEM cats back on for the next test but it sucks I couldn't pass with the high flow cats. Funny thing is they passed me on visual for the cats.
