White smoke from exhaust!

[turbolover]

Hey guys,
My 1993 auto supra is blowing white smoke from the exhaust.It normally emit white smoke upon startup and goes away after warm up.Even during excellaration it does not emit smoke.Original cat which dates back to 1993 has not been change and turbo was service by previous owner a few months back.
Could it be the cat that is too old be the problem.If yes,would i be able to chuck the cat away and replace it with a straight pipe without getting a check engine light?
