Lopaka69,
My 1991 is in perfect mechanical condition w 33K miles. After a detailing my tips are very clean. About 100miles later they are black on the inside surface. Pretty normal if you ask me
I am thinking you do mean the inside surface. In the old days prior to catalysts, you could tell if a car was running rich or lean by the exhaust pipe inner color. A nice uniform gray was considered fine and would even give you an indication of the fuel mixture. Not so any more.
HTH,
