Gets clogged
Normally when catalytic converters become clogged and need replacing there is a reason for this. Something caused the converter to become clogged. Unless you fix the problem the new converter will just become clogged like the old one. If the check engine light is not on and the vehicle is running perfectly with the new converter then it will more than likely pass the smog test.
The oxygen sensor on a 1999 Honda Civic is located on top of the catalytic converter. The catalytic converter is under the car.
Could be a clogged catalytic converter, if you are also getting wose gas mileage, and it sort of smells like raw eggs. Otherwise, I would get a fuel injector cleaning, and try switching to a better octane at the pump.
