When were the DPFs added to the 6.7?

In a discussion with a couple buddies, I was under the impression that all of the 6.7 Cummins had EGR systems, and the DPF and DEF systems came on after 2011. Is this correct? if not, when ? Thanks for any info on this!

My 2008 has a DPF. I think they came out MY 2007.5. The first 6.7's. DEF, years later.

DPF’s came with the change to the 6.7 when they were introduced in ‘07.

Pretty sure DEF was added with the 2013 models.

DPF in all 6.7 DEF came later.

For the pickups.

It was 2010 for the C&C’s.

Our buses got it in '12.

Our buses got it in '12.

But those aren’t a Ram platform, are they?

Absolutely not. Just adding it into the discussion.

for the most part, all diesel powered road equipment in the USA has some sort of DPF as of 2007. If you remember, they mandated ULSD as taxed road fuel at the same time, to prevent fouling of DPF's. Ram is a little iffy as to exactly what model year had a DPF and EGr, just because they had 07 with 5.9 and 07.5 with the 6.7. as far as SCR goes, with Ram it depends on the model... that nice chart in th e post above lays it out better than I can..
