The problem with annoying those folks, is you annoy the very folks who certainly would love to leave you alone with respect to your bike along with them.
Your view isn't a conservative view, it's a libertine view (I'm doing what I want, screw everyone else). The problem with that view is, since you won't take responsibility for yourself (a conservative viewpoint), others are now attempting to do so for you (a liberal viewpoint). Loud pipes may save lives (show me a real, unbiased study that has been published), but vigilance on the road will serve you better. There is a place for open exhausts, at the track, or in the desert.
On my street alone, there are three Harley riders. Two of the three have stock pipes, ride into the neighborhood at normal speeds and have done so for years. The third is an open-piper who cranks the throttle without regard for anyone around him, nor with a care about what time of day, or night, it is. He also whips down the road in a residential area full of kids at twice the speed limit.
But when I go to talk to him about the speeding alone, I'm the one being an "asshole."
Well, if you have already talked to him about the problem, and he refuses to cooperate, maybe it is time to "educate" him.
Sure, you'll have to suck up the assault charge. First offense is usually just a fine anyway, and the neighborhood will probably throw a cookout in your honor.
Respect. Always give it... Always DEMAND it.
