tail pipes

i noticed that my tail pipes become black fast

not like other E55s


is it because more fuel is going to the engine

i remember my fuel pressure is set to (slightly Richer) via star


any feedback is welcomed

a slightly rich set up can also cause it. your buddies may be running more lean than you.
