    I have a 6.4l with egr deleted and 4" straight pipe. Blows light smoke during the first part of accelerating. Runs clean at idle and cruising. Hard to tell smoke color but my bumper gets black so assuming light soot and not steam. Just wondering if this is normal or if I should look more into it.

    Thanks

    I sometimes notice that light black smoke on my 6.0 as well, been some months now without any issue. I wouldn't worry unless it gets more frequent and the smoke gets darker.
