Are there any options to keep the CEL from staying on if you remove the converters?

Yup, there are quite a few threads around here on what to do..

But basically you have two options, you can buy dual output o2 sim or two singles, or use o2 bung extenders to pull them out of the stream, I have had good luck with the extenders keeping the cel off, but if a sensor goes bad it will still throw a code, and the sensor would still need to be replaced, so at that point it would have been better to use a sim since it eliminates the sensor not just tricking it.
