White smoke from De cat Exhaust

  MY04 Scooby STi
Just been stripping the car down for Santa Pod on Sunday. Had the engine on cos I was listening to some tunes. I noticed that the exhaust was pumping out white smoke. It didnt go away once the engine was warm and didnt go away after I blipped the throttle.

Help please, does anyone know what it could be??

probably just some crap burning, out, maybe exhaust sealent junk, or oil junk, probably gets a lt of condensation with this cold weather, so get water in the pipe n steams out ? maybe

definetly just the time of year mate, it will be steam not smoke. My cav gsi had the same problem when I had straight through powerflow fitted.
Used to fill my car park at work with fog lol
