Where there is a will there is a way. You can take the existing muffler and core it out. Then with the addition of some 3 amp resistors fool the computer into thinking nothing is wrong. The only drawback to that is CHECK ENGINE light stays on. I have a system on a cummings that gives no error codes and now I need one for motorhome I'll find one I am sure.
Cummings 8.3 already can be upgraded w/o problems. Search performance products for cummings diesels.

all i have found is pre epa 07 8.3 upgrades, the ones i have found for epa 07 and above do not address the dpf or its removal

my engine has no muffler only the dpf.

if you have a source for EPA 07 engines, please share
