Default Yes...
...have a Tuner turn off the Rear 02s...or, you will see the CEL come on in the DIC, and the displayed Codes will be P0420 & P0430...due to the increased exhaust flow thru the rear 02 sensors after Cats removal.

Slatington, eh? I can't tell from the pic, but is your car a white FRC? If it is, I have its twin in Lehighton.

In addition to shutting off all the related rear 02 sensor codes, the tuner should also disable the COT (cat overtemp) system in the PCM logic.
