Motorcycles and loud/open pipes have been part of the ethos of motorcycling since the beginning. Back in the early 1900's many motorcycles came with exhaust pipes with movable end caps. The caps would cover the exhaust pipe end with a perforated cap for riding in the city, but by moving the cap away from the pipe end it was marked as country. Let's face it in the early days of cars and motorcycles the world was moving forward and if noise was the price to pay for progress, so be it.
Today, with the crowded cities and the " Hey, look at me crowd" the exhaust has taken on a new meaning. The exhaust suppliers adverts talk about the "Growl" and of course the deeply throated rubble. I noticed that a simple slip-on can costs $400.00 to well over $1000.00 to achieve the "presence" that many of today's riders need. What a great many of the new owners don't know is that the new Mega Exhaust system may yield less power due to the computer control of the today's engines.
Loud exhausts for the bar hopping crowd, where the rugged individuals that all dress alike gather is part of the "Hey, look at me" group. This group rarely travels more than a very few miles, unlike the coast to coast traveler that needs the ride to be peaceful. A prime example of the long distance traveler is the BMW, GoldWing owners, quiet, dignified and able to cover 5 to 600 miles a day without the fanfare.
Loud exhausts and motorcycles seem to go together like peanut butter and jam, it has not changed in over 100 years and it will not until the motorcycle riders are banned from riding due to the disruption caused by the exhaust.
A prime example of the change in the world of high performance, look at the race cars of today, mufflers on each one.
I know that image sells and the performance suppliers will run that horse into the ground.
I like quiet, efficient machines.
