    well, some exhaust systems come with a light coating of oil inside the pipes and mufflers. this will generally burn out within a week and everything should be back to normal.
    if not, then you may be burning oil.
    burning oil is the only reason i can think of for black smoke... anyone else?

    an extremely rich a/f will blow black smoke. if its oil you should be able to tell by the smell.
