This is a direct quote from cummins. They say no EGR. And like you said the after treatment system is an all in one now.
Removing Exhaust Gas Recirculation (EGR) allowed us to realize the full potential of the engine for Stage V without increasing displacement size. Our 12-liter engine already pointed the way forward for a successful EGR-free design at Stage IV, so we were able to cascade this simpler approach down through the power range. No EGR also means there is less to cool, which will help lower the cost of OEM integration,” said Jim Fier, Cummins Vice President – Engineering, speaking at the Bauma engine reveal.
He is talking about off-road engines, however even the 15 litre off-road equivalent qsx15 to the on road x15 or isx still uses egr scr and dpf, I believe 12 litres and down the they can get away without egr, but that is only the off-road version, the on highway versions all still use egr hear in North America, however over in Australia they have been running what they cal the isx e5 for a few years, that engine does not have egr and dpf but has scr.
