They have been talking about this on
http://www.usabikernation.com/bikes.asp for a few weeks, saying it was going to come down.....EPA pipe...reads as Stock Pipe......The City of Huntington Beach in CA did a simlar thing, you would get ticketed for non-factory (stock) pipes. They drove the bikes out of town.....
What bothers me is you can be stopped not for sound but if they think your pipe is not an EPA pipe....
