looking at that particular bike, i'm gonna say it belongs to someone in the uk. looks like the taylormade wheels, swingarm and yokes. the exhaust is probably gonna be done be a company called zorstec. unfortunately i think they do all their work one off and need your bike. i tried to see if they could make me the undertail setup that was on the previous owner of my current bodyworks bike. they said they could if i brought them the bike as they keep no measurements. i guess its how they ensure quality fit and finish. if you cant find your answer here try posting the pic on these sites and i'm sure someone will know the answer or point you in the direction of the bikes owner--

be kind enough to take some pics of the install so others can use your how to if they were to buy this setup. always good to grow the data base for fellow max owners.
