First off I love listening to raw exhaust scavenging as much as the next guy. I also understand the fatigue that loud exhaust have on drivers, thus why they all wear hearing protection. F1, MotoGP, and the other serious bar-raising performance classes need free flowing exhaust. But.....there are so many operators that want loud because it sounds fast and makes them think they're fast even though their vehicle isn't and never will be. They're the ones that create the negative perception.......the perceptions start on public roadways and neighborhoods and nurtures a stereotyped anti-noise culture. Very similar situation with off-road bikes and atv's.
Hopefully muffler engineers can bring new products to the marketplace that still sound great yet neutralize the retaliatory efforts of others. It's still the other idiots that never go to the track that will continue to create conflict. As long as there's products that will allow the vested track enthusiasts to carry on and deflect blame and not fuel the track closure movement all is good.
Technology has managed to silence jets, helicopters, and firearms as a few examples and still maintain reasonable performance, hopefully the aftermarket exhaust engineers can deliver as well.
Now can anyone tell me why Harley's everywhere get diplomatic immunity? That's one issue that just flat ticks me off. The epitome of loud and slow.
