Hello to everyone.
I am trying to get some power out of my ADV bike and I want to design some custom headers. Unfortunately, the SD Akra headers won't fit on my bike due to frame/tank differences.

So the plan is to have them custom made. Can anyone give me some info about the headers diameter and if possibly, length? Do the headers have the same diameter all the way up to the Y pipe, or they have multiple different diameters up to that point? If there is a similar post describing dimensions a link would be very useful but unfortunately I have not found anything

Thanks folks!

SD or SDR?

If SDR, I have spare complete set of Akras that you’re welcome to borrow as template but postage to and from Greece.......?
