black stuff under my exhaust
ok when i start my car and let it warm up it leave a big black spot under my exhaust on the ground,it's not a liquid just like a black powder of some sorts....anyone know what it could be...motor is a d16a6...
sorry i wasnt thinkin*to much on my mind* its coming out of the exhaust tip......also no muffler just a cat and 4 in tip..could that be it or maybe the cat is bad????
