Yoshimura R77 Works Race Exhaust System Yamaha FZ-09 / XSR900

The R77 Works Race Exhaust System features Yoshimura's Works finished headers and midpipe that take on a unique coloring after it goes through a heat cycle. This special finish treatment increases fatigue strength, scratch resistance and just looks cool.

The R-77 is serious business when it comes to performance as it was designed with racetrack feedback from the Yoshimura Suzuki Superbike Team. The R-77's trapezoidal shape allows a large volume of packing material and in turn delivers top performance. With a straight baffle and removable low-volume insert, the R-77 muffler's inlet cap is MIG-welded, while the end cap is riveted using high-end 304L stainless steel rivets and bands.


  • Superbike technology and styling
  • Contemporary satin/matte finish
  • Straight baffle for ample flow
  • Uniform heat coloration
  • Increased fatigue strength
  • Increased scratch resistance
  • Stainless steel headers and mid-pipe

High quality
Easy to install and looks great with the works finish. Yoshimura advertises this as not requiring a tune as long as you leave the baffle in, which is nice. The exhaust is a just little louder than stock (with a different sound) cruising around town, but is quite a bit louder when you get on the throttle. love it

Great exhaust, easy install
I have owned this exhaust about 2 years now. It has a very nice tone to it without going overboard like a lot of exhausts do. I do have this installed with a tune form Nels and Kev's o2 mod. Install is incredibly easy, but make sure you torque the manifold bolts down to the proper torque. I have heard of someone doing it by "feel" and they broke the bolt hole. Looks are great, however the only gripe I had about the exhaust was the stainless headers. With this bike they got dirty and often. After a while, I was no longer able to get them clean and the nice shine and purple/blue tinge around the manifold started to become matted and dingey. I solved this cosmetic issue by taking to a local ceramic coater and got the headers coated. That was about a year ago. Have had no problems since. Next will probably be a repack job on the muffler. Overall a great exhaust for the money. I highly recommend it.

Unique looks
Install was straight forward with good instructions. Only additional item I needed was an O2 plug as Ivan's tune omits it. I painted the plug with silver engine enamel to guess the shade after curing and got close but would've been nice to have one included with the same material already coated. Went to great lengths to keep it free of grease and finger prints during installation since I didn't have denatured alcohol on hand to wipe it down as per instructions. Rubber gloves and cleaning prior to install worked great!
Finish after curing is awesome and sound is spot on for my taste. No baffle is deep toned and can easily talk to fellow riders without yelling at stoplights. Can't comment on standalone performance increase as I had Ivan's performance tune done at the same time but the 2 transformed the bike's power delivery and output with no flame throwing and popping! Full on rage is F1 sounding and everyone so far loves it!
My son is saving his penny's to get one for his FZ 09 now! Revzilla was incredibly fast at shipping and as always great to deal with! Love their bucks system! Made their price for it the lowest around!
