The ninth injector trucks have a totally different exhaust. The down pipe is part of the catalyst, and huge because of it. The dpf is a separate piece now, so they came be serviced independently is the way it looks to me.

Found the link here to the 23 plus 6.7 Powerstroke coffee book.
Looks like there is a down pipe like the previous trucks have but instead of a pipe connected and going down to the start of the rocketship, now they have the DEC separate from the rocketship and bolt into the down pipe, then bolt into the SCR/DPF.
The 9th injector looks to be behind, or towards the rear and after the DEF injector.
23s have 3 NOx sensors in the DPF and 4 EGT sensors but they are sensors number 2 to number 5. Has to be one up in the engine bay I'm thinking...
Just where it is, have not see it yet...
