Default Help Passing CO Emissions

Hey all, moving to CO in a couple months and I am trying to figure out how to get my WRX registered there. Currently running catless without issues where I live, but CO has a sniffer test with a dyno.
Considering buying a 2nd downpipe and welding a cat into it, not sure if 1 will be enough and if I should be looking for a GESI / CARB cat?
Any recommendations would be highly appreciated.

Thanks
