Oh wait! The exhaust is laying in my shop! And the truck runs like it should!!!!

Yup you're one of the ones that makes the world hate diesels.
PLEASE explain why. My Son’s truck runs VERY CLEAN.
I think the assumption is that most of them don't. Just too many people think its appropriate/necessary to roll coal. While there trade offs with the current emissions requirements, I for one appreciate not seeing black smoke billowing from trucks, as well as being able to follow behind a diesel and not have to turn my HVAC to "recirculate" to avoid the exhaust smell.
I have to do the same with gassers sometimes. Only difference is I can't see the exhaust, but I can surely smell it. Most direct injected gassers these days blows out a ton of PM, but it is too small to see compared to the bigger particles of the diesels. This is not a good thing because these smaller particles are small enough to get into your bloodstream causing more damage than the larger diesel particulates.
Also, with modern diesels, you would have to be running a very high powered tune or one meant to blow smoke. With much higher fuel pressures, VG turbos, and multi-fire injectors than the diesels of yesterday, you can delete a modern diesel and never see a drop of black smoke. In fact, most people that do delete run tunes that don't smoke. I have to select my 500+ hp tune in order to blow any kind of smoke and even then it it is only a small puff which clears up the second my turbo spools enough air for the amount of fuel I am dumping. All of my other tunes ranging from 400-500 hp do not blow black smoke.
I would bet there there are a lot more deleted trucks around you than you think, but they are not running hot tunes all the time so they are not rolling coal. The old single injection diesels blew a lot of black smoke even with just mild power added due to the low fuel pressure and one injection event per cycle. This caused a lot of fuel to go unburned versus todays diesels that have fuel pressures 10-20k psi higher and up to seven injection events per cycle.
It is that small percentage of diesel tuners that do blow a ton of black smoke and they are no different than the small percentage of gasser guys(although bigger in number) that delete their cats and other emissions stuff to to hot rod their vehicles. The only difference is that you can see it on the diesel, but not on the gas.
Although I will say that my main gripe about diesel emissions is not the DPF that traps the black smoke. It is the EGR and SCR/DEF systems which have nothing to do with black smoke other than the EGR creates more of it when open. If we only had DPF's on these trucks then I would bet that you would see a lot less people removing their emissions systems, myself included. However, in order to remove the SCR/DEF system, you have to remove the DPF as well.
