I imagine that the Triumph/Rocket faithful need to see a pipe exiting on the left. Fair enough. Having owned several Ducatis, I prefer two only, shotgun-style, on the right - so, the Werkes works just fine for me, but I had the rear heat-shield ceramic-coated satin black. As to posters complaining about 'the hole below the swingarm', it only goes to show how used people have become to bikes sporting automotive-sized mufflers, mostly hidden there now. I am and remain pretty chaffed with my Werkes, but it is a tad loud. So,
I have gone and ordered two dB killers for it.
