what year did EGRS , DPF's, DEF etc..show up on DP's
In other words when were the last good non-emission diesel DPs made. I have a 2008 RAM 6.7 with it and I believe it was the first year so I assume a similar time frame for DPs?

Thanks, I had a mental of a large amount of engine rattle, a lot of oil consumption, and parts flying everywhere.
