the air pump injects air into the exhaust gas stream causing the unburnt gases to reburn.  thusly lowering emissions.  If you have removed the dual flow exhaust down pipe etc and blocked off the inlet track into the inlet manifold.

thats a V simplified explanation btw.

Except that 2nd gens dont really have much of a CAT, they work by reburning the exhaust gases in the exhuast manifold...
