I’ve seen it. It’s German and apparently they accomplished to get it ‘accepted’ by the German TÜV (street legal). I have no idea how they did that.
Its even more impressive that they made it with a Euro 4 bike.

You might be rightReally though, it looks like they took a homoligated GPR Powercone, added an extra 30° at the end to wrap it around and then put a longer tip on it.
its ok though... the rider's handlebar mustache will filter out those fumes.I think there’s a reason exhaust typically is expelled out the back. I can just imagine sitting stopped at a signal and having the hot fumes rising up into my helmet.
