If your an owner / operator, straight pipes will save you THOUSANDS of dollars in fuel costs over the life of the vehicle. Straight pipes allow better flow, better flow = more power, more power means better efficiency. When your doing 5K miles / week, that adds up quick. & the jake brake saves you thousands in brake jobs .... & it might even save your ass if your a little heavy!
There are still alot of guys out there who can't afford $250,000 for the latest, greatest,quietest machine on the planet. In the days before electronic fuel injection, the pipes were the first things to go. I happen to enjoy that sound, but as I stand & look around myself, I'm a dying breed.......
When I was living in Phoenix, we used to head out on the bikes to Flagstaff on 89A ( BEST riding besides highway 1 in CA ) & take 40E to 87 thru Payson .... all thru Payson & all those yuppie towns there were signs warning of massive fines for jake brake use. This is just a product of our society today -- people want the entire world to themselves at a time when that is becoming impossible. They have their little bubbles of space, & when ANYTHING ( sound, drivers, off-roaders, someone stopping to read a road map, etc..) invades that space, they revert to their spoiled childhood & whine whine whine
to anyone & everyone. Then public officials become involved & you have signs & fines for everything. If you want an example of the little bubble, just take a drive to any city on the east coast.
