Krumscheid is reliable and make good stuff. I love their gadgets, and they have a lot of sets, parts and also do-it-yourself things.
http://www.krumscheid-metallwaren.de...op.php?lang=EN shows one header which may suit. Search their entire web and you will get what you need.
I highly recommend tunedpipes. I am soon done running in a new MVVS in a small TUG, and using tunedpipe it is pretty close to same power as my DA50 with cannister. Amasing.
Will order new headers and tunedpipes for my 111 bower, gadgets from Krumscheid as usual.
(But you propably don`t like to order overseas?)
