Default O2 Spacers vs Mini Cats

Currently I have the Paragon track cat back exhaust and love it but miss that loud bite associated with full straight pipe.

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?

Mini-cats are the way to go when fully catless. I recommend Big Daddies Garage for o2 sensor spacers and mini-cats as they're about as quality as it gets when it comes to that.

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