Has anyone done any testing on optimum header sizes and lengths for the yamaha r6? I may be building a header for a side car that uses an r6 (not sure of year yet if there are differences) and am trying to get ideas on what configuration is best. I have built dozens of headers for the larger GSXR, hayabusa, zx10r and zx14 motors but nothing for the smaller r6. Any info would be appreciated.
Thanks!
