It's probably a small cat or dpf under there. I figure they can use the heat from the turbo and exhaust to help break down the long chain hydrocarbons and not use so much active regeneration and def...

Dealer told me yesterday that ordering got pushed back until the middle of September and production is slated to start around November 1st
Guarantee Im the only one who noticed this...
But I thought it was interesting how on double cab and regular cab HD trucks, they now get a dual-stage passenger side airbag, with smart passenger sensing system...just like the half tons. Driver side airbag is still single stage.
Crew cab HD's get single-stage driver and passenger airbags and no passenger sensing system, like before.
So the double cab and regular cab HD's get a sort of "hybrid half ton/HD" SIR system. Dual stage with smart passenger sensing on the passenger side, single stage on driver side.
(on the half tons, the driver side is also dual-stage, with a seat position sensor to de-power the airbag if the driver is sitting close or judges to be shorter)
Up until now, from 2001-2016, all HD's have always had the "dumber" airbag system with driver and passenger single stage airbags, and no smart passenger sensing system....the HD extended cabs and regular cabs just got the manual passenger airbag de-activation key switch.
I wonder why? It certainly wasnt for cost savings...having two different airbag systems, wiring, calibrations, R&D, etc for double-cab/regular cab and crew cab. Maybe GM felt not enough people were educated/aware of the manual deactivation switch, and small children were being injured in the passenger seat of regular/extended cab HD's????
Anyway, I thought that was interesting. Too bad Ill never be able to get a real answer, unless someone knows an engineer at GM Safety/Restraints. "NassDmax" over on diesel place works there, but I havent seen him active in a long time.

I wonder how the hell the intake runners are now?? and how the exhaust system pre turbo looks??

It is still normal-flow heads. The exhaust manifolds and up-pipes are pretty similar to the way they are currently.
I really think it'll be easier to work on than the LML, due to the fact that the entire EGR assembly is hanging off to the side, and can be removed as a unit.
Well there already was no room in the valley with a turbo and y bridge and injection pump but now you throw in a pre catalyst lol seems like more of a night mare to me
