usually its just condensation that mixes with the soot in the pipes. but put our fingers on the stuff on the ground and smell it. smells like fuel then you need to look deeper into whats causing it.. if it doesnt smell, then your fine

Re: black stuff coming out my exhaust
Well an old chevy we had burned oil bad...we had to replace the piston rings..and black smoke on throttle was the main indicator in that case...along with a sludgy black soot all over the end of the pipe.....When we replaced the rings the smoke was gone and the soot never returned(after cleaning)....so.......

Dc2012 please dont touch your car.... Black soot is a sign of rich (To much fuel) and white/blue smoke is burning oil... Both can leave soot in your exhaust pipe but comming from exhaust is fuel.
JChope... You had to clean your bumper just to get home.... wtf

Your ring seal and rings and bore was washed down with fuel and washing the oil of your cylinder walls and burning that oil out of the combustion.
There for ruining the rings/ringseal, and burning all of that cyl wall oil out the pipe with it.
This all could have been avoided by having a properly jetted/tuned fuel delivery from the start
