I'm just going to say, that one of the reasons you have a loud motorcycle is so that people can hear you. Not to be an obnoxious douchebag or anything, but because bikes are so much harder to see and notice because of their relative smaller size on the road. Head on, a lot of bikes have a profile no bigger (and sometimes smaller) than a standing pedestrian. I've had people pull out of intersection right in front of me (which is one of the biggest dangers and causes of death and injury on bikes), and I've had people try to merge into my lane right into me. Being as loud as you can is one thing you can do to help others realize that you are there. It's why I took the baffles out of the exhaust on my bike. It's still quite enough to put through the neighborhood without disturbing anyone, but at speed it can make some noise when I need it to.
