There is always someone ready with the "better mouse trap" i. e. some way around the new technology. I'm sure that the new garbage exhaust systems will be "replaced" by enterprising people no later than 6 to 9 months after the introduction of the new engine. The trick will be to keep the costs to do so out of the stratisphere.
Also ... for the enterprising people out there ... there will be a big business in Intake Manifold cleanings for the new trucks. They will get messy fast and kill performance quickly. Or better yet, EGR bypass modifications.
I would hope there are people already looking into this.
For me, the biggest complaint is that Dodge does not make a truck big enought for my tastes. Until there is a 19. 5K GVW model C. C. I can't see purchasing anything from Dodge in the near future ... and my 97 ain't get'en any younger.
