Tampering/defeating emissions systems isn't a grey area. Anyone can likely get away with it in the same way they can get away with dumping all kinds of pollutants into the air/water/soil. The federal government also regulates nox, ppm, etc... https://dieselnet.com/standards/us/hd.php https://dieselnet.com/standards/us/hd.php CARB has more stringent regulations, but I believe most of the companies selling defeat devices are removing the emissions components, not tuning a truck that complies with 2024 CARB standards to instead comply with 2024 federal standards. I think anything built before 1970, or whatever the specific year is, can be legally modified however you want. It's just not legal to take something newer and remove some/all the emissions equipment

IF companies wanted to make vehicles that complied with the diesel emissions requirements of say Michigan, they could make a fully unrestricted diesel. The federal government buys Fords with diesel engines with factory EGR block off plates and no DPF for example. Do as I say, not as I do. Consumer diesel engines had no controls up to around 1999 I think

  Of course they could, but they won't because it breaks federal law. Tactical/emergency/etc vehicles can be exempted from federal and state emissions for obvious reasons, but most federal vehicles are not exempt. > Contrary to past practices, vehicles owned and operated by the Federal government are not automatically exempt from having to under emissions testing and obtains proof of that testing. Some states, in their state regulations exempt classes of Federal motor vehicles, usually those for tactical use. https://www.fedcenter.gov/assistance/facilitytour/vehicle/emissions/index.cfm?&printable=1 https://www.fedcenter.gov/assistance/facilitytour/vehicle/em...
