The all new R-77D muffler has been developed throughout years of racing efforts, and hours of meticulous research and development by Yoshimura engineers. It's distinctive dual outlet end-cap design puts an enticing twist on the style of the original R-77 and further increases the mufflers open outlet area, resulting in increased exhaust flow while maintaining moderate decibel levels.
3/4 System includes R-77D muffler, stainless steel mid-pipe, Yoshimura built under-belly muffler, and all necessary hardware for installation.
NOTE: Please check local laws before purchasing. Some modifications may be prohibited in some states.
You don't know what you are missing
I loved the stock exhaust look and sound. Until I heard the Yoshi in person. It is beautiful and I think it is about 10 lb lighter than the stock one. The difference can be felt but I look forward to do more riding to get more feel of it. The throaty sound is def great over the stock one. this it eh 4/3 system and the exhaust clip is redesigned on this to give the bike more ground clearance but with another winter storm on the way, I have not had a chance to find out (or not find out if I could scrap it). The only thing is no picture to show how much clearance there should be between the muffler to the rear tire and it is pretty close. The installation is pretty straightforward just need a bit more force to take the stock off the header and to push the yoshi into the header. leaving blank on the durability since I dont know. I took 1 off the ease of install because the instruction says to remove the header bolt and let it swing down but it is easier to remove the rear tire to give you the room to remove the stock one.

Easy to install and excellent sound
There are only a few products out there that are designed for the CB1000R. This happens to be the best looking one and keeps the clean look of the single side swing arm while reducing dramatic weight off the stock system and increasing performance and sound quality. I approve. :)

Great looks and sound!
This is the updated version that doesn't have the ground clearance issue the original design had. Exhaust is super light compared to the factory setup.
The instructions say to loosen the header nuts and swing the exhaust down. They say that because the cat is trapped by the rear tire and a clamp that hits the frame. I found it easier to remove the rear wheel and rotate the clamp out of the way, slides right off. You don't use any of the OEM gaskets, so don't panic if they tear.
Looks great with the Cynos matte black. I'm loving it!

Great rumble, easy install
Super easy Install on my '11 CB1000R, snug solid fit, sounds great with a low throaty rumble at idle, looks sick, and a noticeable increase in acceleration "snap". Overall I'm very happy with the purchase (durability not rated as its only been installed a week)

Todd D:That is correct. It dropped over 10 lbs. in total weight reduction and sounds amazing. Very easy install. All parts are included. You will get a small amount of backfire or pop when downshifting, not terrible, but can also be adjusted with a Power Commander or similar system. Throttle response is better with this as well. Hope this helped.Dec 1, 2013
