Probably WON'T pass a sniffer w/o the air pump - the Cat needs extra air to catalise (Burn) the Carbon-monoxide (co) to Carbon-dioxide (co2) and the unburned hydrocarbons (HC) to water (h2o) and co2
so you can see the catalyst needs a LOT of Oxygen (o2) (air = 14% o2) to work correctly.

You will need the air pump hooked up to "legitimately" pass the test. Also make sure your car is completely warmed up -- as in pull into the smog station right after doing some hard freeway driving...
