Default Catalyst converter sensors
If the catalyst converters get removed but the O2 sensors are never touched, will the sensors act and respond the same as if the converters were never removed

the fronts will act normally...the rear will set catalyst low efficiency codes. the purpose of the rear 02 sensors are to check catalyst function.
