Friggin' ridiculous, horrible, and a downright abomination! (Crucify me if you wish, but that's my thought)
Quite possibly not genuine..... Or I think we would have seen in the mainstream. I don't think you need to be technically minded to see that it is 4 into 1 with two outlets I wouldn't have it on my bike, but I like the look!
It would probably look better if the lhs pipe just went under the fairing and connected to nothing. It does look like something that is designed (badly ) cosmetic to look like something it is not,
