Sorry Ben, I'm going to have to disagree with you on this one. It's just more un-necessary crap. EGR, DOCs, DPFs, DEF, etc are all crap rammed down our throats by the tards at the "EPA" who listen to other tards like Al Gore who are running around screaming "OMG!!! GLOBAL WARMING!!". Global warming is a load of crap. The earth naturally goes through warming and cooling trends. Erupting volcanoes dump more "pollutants" out into the atmosphere in one year than we do in a decade. Are we going to start putting catalytic converters on them
? Emissions standards from 10 or 20 years ago where more than sufficient.
The DPF was a "special" load. Soot is CARBON. It'll settle down, wash away, break down and return to nature. It just looks "nasty" (to the enviro-nuts). BTW, what happens when it regens?? uhhh.... More "emissions"? That soot's gotta go SOMEWHERE!
Instead of trying to "clean up" what's coming out, let’s try and change what's GOING IN. This country should be taking major steps towards renewable fuels like Ethanol (which does not HAVE to be made from corn for all the naysayers) and Biodiesel, both of which, besides being renewable, burn cleaner than fossil fuels.
Some may ask "what about smog" and point to LA as an example. Sorry guys, but there are reports back in history of the "smog" hanging over LA from long before the internal combustion engine was ever conceived. I don't recall the exact details, but I believe it has something to do with the topography and the wind directions.
All this crap being rammed down our throats (emissions being only one of the things) by the "government" burns me up. You will NOT see me buying another new truck unless it's a gasser (fortunately gassers have had relatively few "emissions" changes in the last 10 or so years), which isn't likely. If I buy another truck, the ABSOLUTE newest it would be is an 07 Classic. I'll drive my truck until the wheels fall off, put them back and continue driving. The only thing I like about the 01/02/03 Federal LB7's is zero "emissions" crap.
Flame away....
Rant off
