These trucks will haze just a bit, and especially right after you install a new exhaust. The packing oils are being burned off for the first few days. Otherwise, my 06 has hazed since new, even with the cat in place. I have seen a few LMM's do the same thing after a delete too. Nothing to worry about.

this is when warmed up? If so, I would think it were a tuning issue. It should not smoke when warm, at idle.
