What's this coming out of my exhaust..??

It only happens when it first starts up and it's water with some sort of black powder in it..!!

its just where the exhaust gets damp inside and when you start it up it gets chucked out with the carbon build up from the exhaust also

mine does it also.. all over our nice clean expensive freezer in the garage

Hi Jhonno..

Thanks for the heads up.. i thought it was me..!!! Any way of getting rid of it..??

It normaly happens on cars with big silencers, nothing to be worried about. Some silencers have a drain hole. Just drive it and as it warms up the moisture will evaporate. HTH

Cheers guys, you have put my mind at ease..!!

Burning petrol produces water. Lots of it.
When the exhaust is hot the water will pass straight through as steam, but whan the exhaust is cold the warter vapour will condense and get blown out of the tailipe by the exhaust gasses, along with particles of soot.
