Probably a little late for your purposes, but technically anything louder than stock is illegal in Illinois. Which really ticks me off for the 99 out of 100 Harley's that don't have stock exhausts, make three times as much noise as any four banger, but never get stopped for it. So yeah, if your exhaust isn't stock and they think it's loud, they can give you a ticket.
