You can ban modifying your car to pollute more (which we do) without banning modifying your car.

The difficulty against this in the US is the unfortunate reality that the people coming to these shops to enable their stupid trucks to roll coal are the people who should technically be raiding and shutting down these companies. This can be fixed.
Physically, you can already modify your car to be controlled by a stupid program and that has been possible since at least the 90s. You can do the supposed harm by not being aware of damage to your exhaust system.
The solution to exhaust harms of ICE engines is electric cars, not a reduction in consumer rights.
The EPA heavily regulates any emissions defeat devices. The problem is they spend most of their time going after tuner shops where most cars run on ethanol rather than diesel shops who cater to brain-damaged customers who think rolling coal is "cool"
