I am really surprised that short of a cut out on Harley's some sharpie doesn't come up with a dual range muffler system. Something like that would be popular with the "today I'm closing up my _______", going out and be a Harley bad ass because everyone knows that loud pipes are loud pipes. Then when I pull into the cul de sac the neighbors won't bust my chops because I caused their Chihuahua to crap on their Astroturf.
The local sheriff did the same thing in South Carolina about 5-8 years ago and had the staties with them in the beginning at a poker run in to a fair grounds. After the staties saw what was going on they left. The shit did hit the fan and the sheriff got deposed. But it took about two years for that to happen. The reason being the cops didn't realize judges and lawyers rode motorcycles too. Backward police practices and thinking!
