I have been running one of these on my Speedster for a few years, they look and sound great. I wish they were available over here. One good point, I recently had an engine built up by Steve Schmidt at Honest Engine and he was impressed by the power that a motor running the exhaust could generate. From his perspective it was one of the better exhausts of that type.
