So you mean getting rid entirely of the DPF and SCR? Unless you really don't care about liability issues, I'd suggest you to take a look at what has been done by some truckers in Europe in order to straight-pipe modern trucks and not get in trouble because of a DPF and SCR delete, they're fitting exhaust diverters leading a smaller amount of the exhaust flow to the aftertreatment module. Not totally legal though...[/QUOTE]
Fit in the truck with an SCR and DPF from Cummins. The factory exhaust on the ecodiesel is 3" vs the Cummins 4". Just need to fab a turbo down pipe and new hangers.it will be straight piped after the DPF.
