i noticed this problem also when i removed my CAT. so im pretty sure its just because the cat has been removed and no longer filtering.

Having owned plenty of older cars (pre-cat), old Ford RS's for those in the UK nd in the know. A small amount of white smoke on start up is generally just water residue or condensation caused from the car being sat, and the water burning off after start up. If it clears quite quickly I wouldn't worry too much about it.
I'm preparing to get flamed for being a 'noob' nd putting my 2 cents in.
