No, since other categories of vehicle behave in the same manner (the very large population of quiet ICEs). Thats what makes it unconstitutional. And legal laws are the only ones found unconstitutional, btw. Being constitutional is so *inconvenient*; it is more politically effective to pick an unpopular group and aim the legislation directly against them.
Example of a constitutional law would be the 85db noise law which is often posted on signs upon entering a village or special district. It is fact based and applies either to all vehicles or else only to the type specified (or pictured) on the sign e.g. dirt bikes.
