So I took the car for long ride (about 250 mi) speeding constantly at about 60-80 mi/hr with some WOTs. Everything looked fine, RPM is at 2.6k-3.2k at that speed, coolant temp at 200-205 and so on. I filled the car with gas and hit the way back home (another 30 mi). When I parked the car and next day I run the car and it threw black chips (small black residuals ) with water from the exhaust tips. I didn’t notice any smoke only that water mixed with black chips as the car was warming up to the normal temperature(maybe 10 mins and getting less gradually). I took the car for a short drive and everything looked normal.
Is that something normal after that long drive?
The car is 1990 Mustang manual and it has many modifications. Exhaust system is Hedman EL Headers, Magnaflow Xpipes (no CATS) and Magnaflow Cat-back. I really don’t use this car as a daily driver.. maybe once or twice a week for about 10 mi.. and warming up from time to time.
