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 polished stainless steel rivets and bands.
This Full System features the R-77 muffler, stainless steel headers and tail-pipe, step-by-step instructions, and all necessary hardware for installation.
Note: Please check local laws before purchasing. Some modifications may be prohibited in some states.
Perfect fit, easy install, excellant finish
All though price was why I chose the Yoshi system, I was
not surprised by the quality product. Hardest part is removing original exhaust, Installation was straight forward with no problems. Finish is super turns slightly gold after a few heat cycles. Best of all is the sound even with baffle inserted.

Instructions were good, install took about 60 minutes. You may want to cut down a 5mm Allen wrench or use a ball-ended one.
Instructions were good, install took about 60 minutes. you may want to cut down a 5mm Allen wrench for the oil pan bolt above the new pipe, or use a ball-ended one. Stainless header is a thing of beauty. It yellowed a bit after riding the bike but it looks cool. Best part is the sound; the beast can now be heard! Awesome exhaust system!

WOW - Sounds amazing! Easy Install!
Just got this exhaust in today. Had it installed on the bike in about 1 hour. Fits like a glove, high quality materials and AMAZING SOUND!!!! So far absolutely thrilled. I left the baffle out for a deep rumbling sound.

Alex G:Technically you don't need to remap the ECU but as is typical with new aftermarket racing exhausts your bike may spit and crackle a little bit . If you don't mind that (i personally like that sound) then don't worry about tuning the ECU. However in general i have to say that from what i hear on the forums the FZ-09 rides way better if you flash the ECU at Stoltec. Supposedly it gets rid of the herky jerky throttle response on the bike. At the same time they can probably tune the ECU for your new exhaust.Jul 17, 2014
Jon M:My FZ09 ran fine after the install, but it seemed to have a slight loss of power at higher RPM's. I plan on getting a Power commander as soon as they make a high flow air filter. The bike is still too new. The exhaust looks and sounds awesome. Revzilla shipped really fast and packaging was really good.May 31, 2014
Linh N:I haven't bought this one personally, but I can tell you that carbon fiber exhausts manage heat 'very' well. I have a carbon fiber exhaust for my ninja 650, and after a day of riding, I wouldn't be afraid to put my entire hand on the carbon bits. However, carbon fiber is more expensive to produce, so if you're trying to keep it cheap, I'd stay with stainless steel.
PS. even if the entire muffler body was carbon fiber, the weight reduction is minimal.Aug 14, 2014
