that is carbon deposits, looks like your car is has been running rich for a while, till it spit out all the stuff when ya reved it good.
Its carbon and condensation in the exhaust. The condensation is water thats spitting out the sutty insides of the exhaust. My exhaust does it every morning and almost everytime on cold start. Its nothing bad. I got those little marks all over my driveway, it looks funny:p
Bless you:p
nothing to worry about:)
