No EGR or CAT if that is what your asking, I think they added the CAT at 04. 5.

diddo to above... cats came on all 04. 5 and newer... i believe the 5 states emissions versions got cats from 03 and up, but still no egr systems on any [5 states being cali, ny, mass, maine, ct?]

Thanks for the info one and all... do any of the cummins have egr after '03?

not in dodge's application. the egr may never come into the dodge trucks as they can meet tier 3 spec emissions with the in combustion technique [3rd pulse of fuel] and cats... for tier 4 [2010?] they would probably need it, unless they go camless with electro-hydraulic valve actuators, then they can do something like CAT is doing with their acert... but by that time, somehow i fear there will be a MB diesel engine under the hood...
