Don't forget, CARB is not federal, yet their rules and regulations are given serious consideration as they are one of the largest US markets plus the fact that some other states just adopt that CARB puts out.
As for removing emissions equipment....ROFLMFAO. See how far that gets you. In my state, it would not matter if the second coming happened and Jesus himself declared that DEF and DPF were optional and no grandfathering exists on a national level, the DMV would still expect to see my truck with that equipment. The only thing more outlandishly unlikely to happen would be for the bears in the chicken coops to dip your tank, have it come out red, and just wave you on.

I am not sure if you lived back then, but the air quality in places like LA, Chicago, New York, etc was just absolutely horrible.
I remember when people talked about removing catalytic converters like you are talking about removing DPF. "Just cut it off, it doesn't add anything." Yet anyone who has followed a car from the early 1970s (or even a mail truck) can tell you that there is a significant difference in the quality of the air between that pre-catalytic converter vehicle, and a modern pollution controlled car.
I know some people love to "Roll Coal", but that is the exact thing that a DPF is supposed to prevent. I remember driving a 1981 Buick LeSabre (with the GM 350 diesel) and how much soot that thing would put out...and it didn't even have power (110 hp, 210 ft-lbs of torque) available to it...
Now imagine just how much would come from the Semi, medium duty, and "heavy/super Duty" trucks out there if they didn't have DPF.
I used to have problems breathing when a truck would roll by and that exhaust would come out. Now that doesn't happen.
Please, don't let history repeat itself. DPF and DEF have significantly improved the exhaust of diesel vehicles.
If you want to see an honest example of how bad pollution could be in the 1970s, go look at the opening of Blues Brothers. It's an ariel shot of Joliet at that time. Between the refineries, the power plants, and the traffic, you can almost chew the air. I will be the first to admit that the film has not aged well in all respects, but that opening shot is not an exaggeration. Thing is, controlling pollution needs everything to contribute. It's not just a "only do refineries, only do power plants" It requires the transportation industry as well.

Today’s diesels are not your gm 350 you remember back then that just shot a squirt of fuel in at almost tdc and what did not get used went out the tailpipe.

There are two things that you have wrong. One, I never pay the average retail price that you use, I have the OR discount that typicially is only $0.30 - $0.40 a gallon over the cost of regular gas. Two, I paid cash so finance costs are zero. I will also probably keep this truck for well over 200,000 miles or ten years.

Late 90's, early 2000's, diesel engines were plenty clean. DPF and DEF, have gone too far. Common rail and EGR is fine.
As far as smog in NY and LA, I dont care. Ban all cars and trucks in those cities. Screw them. They can do whatever tney want. Just leave the rext of us alone.

The ‘70’s are long gone. Horse crap in the streets was a big issue before that too. Poorly tuned carbureted cars that burned oil after 40k miles were to blame. Not diesel pickups, which weren’t even a thing back then.

@ATC Crazy Thing is, diesel smoke/particulates are part of the problem. @Just Chilling said above that just a tune and pulsed HP injection would prevent it...If so, why are they not using it? Even if a DPF was mandated, if just those two things would fix it, they could put the particulate filter on it but never need a regen cycle, right?
Have things improved? Yes, but it's because of the entirety of things. It's not one thing alone, and that includes DPF and DEF. I get it, you hate them. Neither has caused me headaches, but those folks that love to roll coal? Those people can cause me to cough for a week just from being behind them a few minutes. I have no problem if you or someone else finds a better solution than those two, but until then, I am fine with it...

EGR is the worst thing you can do to a diesel. I have seen 6.7L Powerstrokes with almost completely clogged intake ports. It was a wonder they were running at all.
DPF's and adsorber catalysts did a lot to clean up diesel emissions, but they are not maintenance free. Adsorber catalysts permitted less reliance on EGR to control NOX, which really helped performance. Sticking with EGR technology took Cat out of the truck engine business and nearly backrupted International.

was picking up my kiddos from swim practice, sitting in my 02 F350 7.3 idling, waiting (ex-wife is crazy, always made the kids late) had an older lady come out, walk to her car, walk BACK to me and TELLS me to turn off my truck... SHE has some effing alphabet issue and
MY truck is causing HER problems 
I was sooo worried for her (it was a nice gentle breezy day) that I told her GFY and went back to my work call I was on she interrupted, had to roll up my window so I could continue a conversation she interrupted by walking at LEAST 40-50' from where she was parked, to demand I turn my truck off to accommodate her... SMFH! She probably wore a mask 24/7 even when in her car, by herself, to virtue signal how compliant she was... I'm not sorry, the world is NOT here to accommodate you or anyone else FFS!! Don't like the air/atmosphere, move, so tired of all these crazy yucks bitchin (is that ok to say?) about THEIR AIR, like no one else is living in the same doggone place, you have issues... move to somewhere you don't, NO ONE has to conform to YOUR problems. I'll bet 100% of the folks B- itchin about the problems here have NEVER spent any time in any other country and have NO idea just how great and amazing it is here in the good Ol'USA! Try whining in some 3rd world S-hole and see where it gets ya! Sorry, stepping down off soapbox now...

In California they are still everything that is not working right on Ronald Reagan. I think these people are just stuck in the 70s from using too much mind altering substances such that they forgot 90s and 2000s existed.

Pickupmanx2 has it right. No one thinks about the manufacturing process emissions or shipping emissions.
1966, with new every five years is 12, that’s a lot of manufacturing. The pickupmanx is the true eco-warrior.
It’s a very unserious time with a quick to judge, quick to anger and a slow to understand populace.
Yes, I need 1k pound feet to pull my John boat to the river.
Yes, I’ll buy socialism from an immoral capitalist who generates 30 million in 6 years. Look at me on my insta, not your property tax bills.
Thank god I’m old.
