How many 02 sensors?

does my 2000 civic ex have 1 or 2 02 sensors? I was at autozone to buy a new one for my new cat and they was showin that theres only 1. If theres only 1 then how come when you buy new dc sport header off ebay they have a bung for an 02 sensor?

A 2000 Civic EX has 2 O2 sensors one on the catalytic converter and one on the Header. Someone at autozone needs to find another job or computer.
