Since your primary cats are not present the post cat o2 sensor is triggering the CEL.
This condition may affect your long term fuel trims, better to have the post cat o2 sensors turned off.

Whatever we're tuning!
When the K2 package is done the ECU needs to be sent to Cory so they can adjust the values in the ECU to account for the cat delete.
They are not shut off like so many novice members think. The signal is still present but the ECU is told to ignore it so you do not get the CEL.
If you are getting these codes the ECU needs to be sent back to Kleemann for the secondary O2 sensor parameter update. Good luck!
