I think people here are thinking that I am talking about going to extremes and removing all emissions parts. I am not. As I stated before, emissions regulations are good, however, there is a point of little return for the amount of money spent and added pollution required to achive such small numbers. In my opinion, that was anything passed the 2004 standards.
There is only a 1.8 g/bhp-hr difference in PM and .8 g/bhp-hr difference between the 2004 and current standards and yet it causes less reliable vehicles, added pollution from less fuel economy, plants to make DEF, trucks to transport DEF, plants to make the plastic DEF containers, landfill pollution of the plastic containers, pollution from the material mined to make the DPF/SCR catalysts, and so on. All of this wasn't even thought of when EPA forced the manufacturers to attain these numbers, and they certainly did not go back to see if what it took to attain such a small difference was worth what it took to get there in regards to the added pollution it created.
Besides, it is dang near impossible(and costly) to remove all the emission parts on a 2011 and up trucks. Yeah, you can remove the EGR, DPF, and SCR, but these are just external devices. Then there is the VG turbo itself, the common rail fuel system, multi-fire injectors, the cam (which is specifically designed for emissions), and a few other parts. Then you have the diesels itself which pollutes less than 20 years ago. This is why even a deleted 2011+ truck emits less than a pre-2004 emissions truck with all of the emissions devices on it. The only way for you to roll coal is if you purposely program it to do so which I am also against. Heck, even direct injected gasoline engine emit more PM than the 2004 emissions and there are way more of them around most of you than diesels.
