If you're looking for that competitive edge, look no further than Yoshimura's Race Series exhausts. These exhaust components are designed with nothing but power in mind. Each Race Series system is developed in accordance with noise compliance regulations imposed by most race sanctioning bodies worldwide.
Yoshimura created the R-77 full exhaust system to match the radical design of the modern motorcycle perfectly while at the same time removing heaps of weight, adding power and giving your bike a distinctive deep exhaust tone.
The R-77 muffler consists of a trapezoidal-shaped sleeve, maximizing muffler volume while offering a sharp silhouette to flow with the body. The innovative end cap is reminiscent of the Yoshimura R-55 exhaust system, featuring sharp edges for an attractive, eye catching appeal.
Full systems include an R-77 muffler, header and mid-pipe, along with all the necessary hardware and clear instruction for simple installation.
Stainless steel headers and mid-pipe
Trapezoidal shape R-77 muffler

Innovative end-cap shrouds the terminus of the muffler for an unmistakable look

Don’t waste time installing a product that doesn't fit. We worked hard ensuring that this product is an exact fit on the vehicles listed below.
Yes, if you were to choose the 2013 Suzuki GSX-R750 Yoshimura R-77 exhaust system from our fit guide, you'd receive the correct components to fit your machine.
Will the 2016 FZ 07 have to have the ECU flashed when this exhaust is installed?
By FZ 07 Lady
While it's not required, if you want to get the best possible throttle response and engine power output upon the installation of any new full Yoshimura FZ07 exhaust system, we certainly do recommend that the bike's fuel delivery be modified to suite the change
in exhaust flow. The good news is that the bike is equipped with an oxygen sensor in the exhaust, which feeds data to the ECU, so it will compensate, somewhat for the new R-77 Yoshimura Yamaha FZ07 exhaust system. Whether or not it'll be enough is hard to say, but signs
that the ECU can't keep up with the aftermarket exhaust are things like stumbling at a steady throttle or when you make small changes in throttle position.
In the instance you do notice that the bike doesn't respond to throttle input the way you'd like after putting the exhaust on, we recommend the Bazzaz Z-Fi fuel controller for the FZ-07. It comes equipped with a fuel map for use with a slip-on muffler,
but it'll certainly be better than the unmodified ECU. Still, you'll need to take a trip to the dyno in order to have the FZ07 Bazzaz unit tuned to get the most out of the exhaust.
Will this require an ecu flash and or fuel controller to work on fz09?
By Jeru
While it's not required, if you want to get the best possible engine performance and throttle response out of your FZ-09, you'll want to adjust fueling accordingly. Basically, any time you change the way air gets into the motor or how exhaust gases get out of the combustion chamber, you should adjust fueling to suit if you expect to get the best possible power output for your investment. Still, you can try running the bike without adjusting fuel to see if performance is satisfactory.
Should you decide that the bike could be running better and want to get a fuel management system to go with the exhaust, we recommend any of Bazzaz's fuel tuning systems to fit the FZ-09.
I have a 2015 GSX-R1000 with the Bazzaz Z-AFM on it. Will the O2 sensor from that kit (threads measuring M18 by 1.5) fit into this system?
By tyler
Yes, it will fit. All Yoshimura R-77 Race Series full systems are designed to fit the OEM oxygen sensor. In the case of machines equipped with a M18 x 1.5mm from the factory, Yoshimura includes an adapter to fit the smaller M12 x 1.25mm O2 sensor.
