White smoke at startup from exhaust?

Noticed twice in the last week a puff of white smoke when i start up the engine. Anything to be concerned about or what this suggests? I have AWE sport cats on my car. No CEL light or anything.

A common with flat 6 boxer engine, your car is fine just make sure you have the proper amount of oil in the car. Enjoy that AWE system

Agree. This is normal on a cold start. Especially after sitting for a couple of days. Make sure your oil level is not over filled.

sclemmons is infamous around these parts

If it is white smoke, my BMW experience tells me it is water vapor.
Black = fuel. Blue = oil.

I may have them mixed up but I am pretty sure white is ok on chilly mornings. Even on a Porsche.
