New Member Into, and looking for 2 into 1 header for SOHC XS400.

Good evening! Happy to see a space for these bikes and own a '77 XS400D. Going to be working on a project over the winter and hoping to find a 2 into 1 header to purchase rather than having one fabricated, but will resort to that if needed. They seem to be out of production from MAC I assume? I specialize in cylinder head and valve train work for vintage Japanese bikes as well so willing to buy or trade work for a header. Could also use a second complete engine but pretty sure that's hard to find and have shipped, especially the 2A2 D model with the squared off fins like I need. I'm wanting to leave the working engine in frame while building the second one so I can keep in on the road. Thanks in advance!

 

Yeah I figured that would be the case, thank you for the response! I guess the plus side of custom is I can have an O2 sensor bung included for tuning.
