@JT700: It´s an GPR Exhaust. In Germany you can get it at
http://www.gpr-deutschland.de or
http://www.bikersandmore.de (the last one is the better one

) The manifolds are available at tunebike or ABP..... maybe in other firms too......they cost about 150 Euro, the GPR 390 Euro if it is made of stainless steel. You can order that thing in Carbon oder Titan too, but then it´s much more expensive.
If you mean it gives you some extra horses I must disagree, it´s like driving the original one (not many exhausts are on the same level with the original)....only awesome loud, even with the db-killer
I guess that you should geht the carb at the Mikuni importeur of the USA. Ask for a Mikuni TM34B65....but please sit down....that f*ckin´ carb costs over 500 Euro....
