O2 Spacers vs Mini Cats
So picked up some 2M cat delete pipes. They came with the O2 spacers and I also ordered the mini cat spacers as well.
The question is, should I go straight for the mini cats or try the spacers first. I know most people had luck with the just the spacers and no CEL but for me logic would say do the mini cats. In my mind the idea of the mini cat would be more robust and would convert the gasses for the secondary O2 sensory however I could have sworn I read on the forums somewhere that some people did not advise mini cats as it can’t change secondary measuring in an unfavorable way!
So should I do spacers or mini cats? Do mini cats truly change secondary measuring in a unfavorable way?

Valve simulators are in no way related to the o2 sensors.
