You will never be able to buy anything unique for a "mass produced" price. If you truly want "unique" you will have to pay big for a one-off custom build.

Are these the mufflers which end in a Gatling gun barrel arrangement? I have only seen one bike around here with those and never saw it run. Perhaps the rotation rate would be more equal with true duals. With the factory arrangement with most of the exhaust coming out the right, and a little from the left, there is bound to be difference in flow and rotation speed if driven by the exhaust flow.
