    Yoshimura R-77

    Was Windering If Anyone Preordered It Or Not? Can Looks Different & Header Looks More Straight Then A Loop. I Might Wait Till It Releases And See What Others Think About It VS The RS2 That's Already Out.

    It has to be more of a top end pipe than the RS-2.

    Here are the dyno charts from Yoshimura's website.

    Webike has all but the blued Ti in stock. The R-77 is the way to go if you want Yoshi... good choice!

    I don't get the preorder thing, the R77 has been out for years, since 2014 I think.
    I also really like the high mount R77, the header is very nice. It's not listed on the japanese Yoshimura site so it looks like weblike is selling the last ones.

    I don't know why they do not offer it for the OG anymore, makes no sense.
