kate, hows it going. the cats wont smoke. you engine it sending that through your exhuast. the cats will break apsrt and clog up the pipes but wont smoke.
i think white smoke is a head gaset.

if the cat is smoking its because something is touching it and is burning off. Maybe you ran over a plastic bag on the freeway, its happened to me before.

check to make sure your 02 sensor wiring isn't touching the pipes.
