Noise abatement is a reality today. Setting up concrete barriers between Interstates and housing developments built next to them. Noise abatement zones around airports, etc. The city I live in, Fredericksburg, VA, has a major road, US3 that runs through the northern portion of the city. There is one place where you go down a slight hill and off to the right is a sign that says, "Residential Area, No Engine Braking", aimed specifically at the semis, dump-trucks, etc, that use their engine brakes and cause the loud back pressure popping from a diesel engine. That's the only place I've ever see a sign like that, and the truck drivers respect it and I've never heard a deisel use engine brakes when I've been in that area. It boils down to being responsible and it's our obligation as the owners of motorcycle, diesels with engine brakes, or whatever, to operate them responsibly and respect the rights of others as we expect them to respect our rights to have freer breathing (read louder) exhausts on our bikes. If you've just got to crack that throttle to show off your pipes, do it at a rally or go out into the country where no one can hear you and crank to your hearts content. I don't have louder pipes on my HD's because I believe for one minute they save lives. I have them because I like the sound and the performance gains I get, but I also know with that extra sound I have to be a little more responsible in how I drive it. When I'm leaving for work at 5:30am, I try to get out of the neighborhood with minimum throttle to keep the noise down. I've never had a neighbor come up to me and ask me to keep the noise down when I'm riding. My one neighbor across the street was very nervous when he moved in and found out that I was a Harley rider. He even asked me if I had loud pipes on the bike. I talk to him all the time and he's never once told me that he thought I was too noisey when I rode the bike. It's on us folks, either we take it upon ourselves to do it right, or we'll get forced to do it right. My $.02
