Tens years ago, I would have approved of such measures, but loud pipes are your friend. Yes you.
All around the world, LEOs have become conditioned to equate noise with speed. It's as if nearly all of the other gazelles on the serengeti plain have voluntarily donned belled collars to let the lion know that dinner is on the way.
This is why I wave to every Harley with straight pipes and everystuntah on a beat-up crotch-rocket with an aCrapovic pipe I pass (most of whom do not wave back, but I give the opposite of a f**k): they have all paid for your stealth bike, and they are keeping the lion well-fed so that you are free to go about your business or fun unmolested.
Always wave at these brave souls, and don't expect a wave back. We owe them so much.
