EPA, through its direct implementation authority, can play a critical role in addressing these important pollutant sources. Title II of the Clean Air Act (CAA) authorizes the EPA to set standards applicable to emissions from a variety of vehicles and engines. Required emission controls often include filters and catalysts installed in the vehicle’s or engine’s exhaust system, as well as calibrations that manage fueling strategy and other operations in the engine itself. The CAA prohibits tampering with emissions controls, as well as manufacturing, selling, and installing aftermarket devices intended to defeat those controls.
The EPA has found numerous companies and individuals that have manufactured and sold both hardware and software specifically designed to defeat required emissions controls on vehicles and engines used on public roads as well as on non-road vehicles and engines. Illegally-modified vehicles and engines contribute substantial excess pollution that harms public health and impedes efforts by the EPA, tribes, states, and local agencies to plan for and attain air quality standards.

The companies mentioned were in blatant violation of the law, period. You see these monster diesel pickup trucks everyday.
But this is leading to an over-reach whereby hobby/historic vehicles will be affected in the future.
I fully understand the needs for emissions law. I also understand trying to modify/defeat emissions systems on cars. But this is leading to the same situations that were encountered years ago with mechanical emission systems and not being able to legally modify a street car without a parts CARB EXEMPTION.
The reason for not being able to modify a street car for RACING USE ONLY is a method of them controlling any modification(s) to an emission system on a street driven car.
