I have black blumes of smoke coming out from my exhaust. Now mind you I was the one sprayed Eagle One wheel cleaner up my exhaust and cleaned it out, loosened soot and now have black stuff sticking on the back of my car.

Anyways, any ideas on what this could be? TIA

BTW, Audi '91 100 stock exhaust + performance OBX muffler.

Mine stopped when i replaced my Catylitic converters.

and if so, I guess I'll either have to fork the dough for a Scorpion Exhaust w/ CAT huh? :(

Check to see if you are using the correct weight motor oil, and make sure that your spark plugs are good (make sure no misfires or partial fires)
