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
