Hi, I've had my STi for about a year now and I have not encountered this...... a puff of white smoke comes out when starting the car... smells like burning. Anyone know what's wrong?

A simple search will yield results. White smoke =water
Black smoke = fuel
Blue smoke = oil.

Im not sure why it smells like its burning though. It should smell a little 'sweet'.
How long does smoke come out of the pipe? If it does happen, it should happen only for a second or two right when you start her up.

when i was catless.. i had some issues with this... never really was a problem tho. If its a heavy amount of white smoke theres probably a coolant leak somewhere or blown head gasket... but i wouldn't worry if i were you.

A cat only works when its at operating temp. It will be no where near this on a cold startup.

hmm... it only happens for few seconds....

I don't know why.. it smells pretty bad tho. Does oil level too high have anything to do with this?

It's condensation. I had this happen a few times when it was extremely humid outside, and I started her up.
