As I understand it, modifications to or removing emissions control equipment is illegal for vehicles registered and driven on public roads. Always has been. But there has always been a "legal for off road use only" exemption for race cars and other off road competition and recreational use vehicles that were once federally certified, but are no longer used on public highways, and the parts and pieces used to build such vehicles. That was Congress' intent. EPA intends to eliminate that exemption.

Think no more big blocks in slant six Dusters, Stockers or Super Stockers that were not factory race cars, fast "street" cars built on OE bodies, etc. In other words, your '73 Dart or '82 Camaro or '89 Fox body Mustang has to remain as it was built and certified for federal emissions.

I have no idea of what they think will happen to all of the cars this will affect. Anyone who has dealt with trying to get a car inspected that had the AIR pump or the cat removed or failed an emissions inspection and had to either fix it, junk it or pay some kind of penalty, can use their imagination. I can assure you, dealing with the EPA will not be like dealing with your buddy down at the shop when you get your state inspection done.
