AFAIK some truckers are running a bypass system that re-routes part of their exhaust flow to a straight pipe while a smaller amount goes through its aftertreatment system, but that's mostly for the sound of a straight-pipe. I'm sure any attempt to "roll coal" would not be worth the risk of ruining the DPF and the SCR core.
