“Would this also apply to ricer cars with coffee can fartpipes?”

And cruisers (ie Harley-type bikes) with straight pipes?

And, for that matter, muscle cars and pickup trucks with really obnoxious “free-flow” exhaust systems, and also commercial trucks with the mufflers removed (so when they hit the Jake Brake it just about blows out the eardrums of anyone within a mile’s radius)?
