As stated in the previous two posts, it's merely eye candy.
I bought a dual can setup a few months back
(IXIL $750US) and ran it for about a month.
Did I like it: Yes, I loved it.
Why did I remove it: Functionality. I also have a 3 bag setup from Givi and with the high mounting of the pipes it prevented me from mounting the wingrack.
So, basically I loved my bags more than the eye candy.
One thing I will point out that I noticed was that there isn't even flow with that setup. Meaning the pressures exiting the cans is dramatically different from one to the other. The right side can still handles the most gases. Does it matter or effect performance, No.
I've tried contacting BanditMania myself about there pipe work for a standard mount where I could possibly still use my setup, but never received a reply.
