E63 running rich??

I have noticed this on my exhaust pipe tips that there is a black(carbon?) on the lower part on all four tips. You can clean them with chrome cleaner, but they start to get black again in about 2 tankfuls of gas. Is this normal, or do I might have a car that is running a little rich, and if I was, how could you tell? Maybe this is perfectly normal, and maybe not.. Just wanted some comments for guys who might know!!

My 55 had the black, my 63 seems to have less of a problem on the tips. I thought this normal due to exhaust containing carbon

My exhaust pipes are black on the inside, too. They clean up a bit when I wash the car. I think it is from the A/F mixture going rich under load to protect the engine. Chrome cleaner is cheaper than pistons.

Do not worry about it, that is normal. 63s are set-up rich from AMG.

Sounds dumb but maybe they did not put enough oil back in it. That happened to me with old C55.
