Downpipe CEL and emissions readiness

So I found out recently that just because the post cat sensors are removed from monitoring, the emissions readiness does not complete.

After speaking with someone they recommended these mini catted plugs that they have had luck with on BMWs.

For my recent tune I asked the tuner to not delete the post cats.

I'll try these mini cats out and post back in a few weeks once the system is able to run thru the cycle.
