i have a full sportex system we it goes to the Cat. but as soon as i have washed my car an drove a couple of miles the back of my cinq sporting is covered in black specks of what looks like oil??? what does this mean.
help!!!
cheers zoe

it could be bits of carbon, car could just be overfueling a bit.

If it only appears just after you've washed your car , it sounds like water has got into the tailpipe & is simply being blown out . This is especially likely if your exhaust is upturned

You sure its not just dirt off the road?? :chin: lol

If the car is running ok it shouldn't be anything to worry about
