Why doesn't it exist?? Sorry to keep preaching about quiet pipes, but I just recently got a complaint about the noise of my bike while riding on some vacant land in Loveland, CO. I think it's only a matter of time before we can't ride there anymore either....Why? Because our bikes are too f'ing loud!!! If they were quiet and the people in the nearby (newly built) subdivision couldn't hear us, we could ride there all the time until...they build another subdivision (on top of our nicely built table tops).
