The R-77 exhaust is Yoshimura’s flagship model and the same design they use on their AMA Superbike Championship-winning motorcycles. What’s especially interesting about this exhaust for the CBR1000RR is the tuned-length design of the midpipe. With this plumbing, power output is significantly improved between 3,000 to 9,000 RPM on a CBR that has no custom map. You can imagine the extra power available with a Bazzaz or Power Commander system and a proper map! This muffler is available with either a carbon fiber, stainless steel or titanium sleeve that’s capped in carbon fiber or an all-stainless version. The slip-on also comes with an all-aluminum heat shield to tidy up the look of the lower end on the Honda.

We do not have these on our website yet - call TJ at 866.931.6644 ext 817 to order. As always, shipping is free to the lower 48 states. If you prefer, send email to FORUM at RIDERSDISCOUNT dot COM and please specify the year and model of motorcycle you ride along with the type of muffler sleeve you prefer.

Everything that comes in the box: heat shield, muffler, clear instructions, a sound baffle (for those of you concerned about noise) and even a nice exhaust spring tool.

Yoshimura employs a CNC-milled exhaust hanger bracket. No, it’s not the cheapest route, but it is sturdy and looks good.

The s-bend midpipe permits installation of the OEM Lambda sensor or one from either a Power Commander AutoTune or Bazzaz Z-AFM.

As usual, Yoshimura construction is top notch.
