Yes, besides the manifold/header pipe mounted O2 sensor, the OBD2b Engine Management System on your '01 requires one also mounted after the Catalytic Converter.
I have to modify my post, because - in fact you didn't id your ride in your text.
If it is an OBD1 system, it does NOT require a second O2 Sensor

An airtube is a port on the converter case which allows a pipe from the A.I.R. (Air Injection Reaction) pump to inject a fresh air supply into the converter. The '94 Accord is not equipped with an Air Pump, Thus you will not need a converter with the pipe provision.
