Yoshimura R77 Race Slip-On Exhaust Honda CBR300R / CB300F

The Yoshimura R-77 Slip-On Exhaust was designed with the needs of the racer in mind. Using the feedback received from the Yoshimura Road Racing Team, their designers came up with a muffler that is constructed from lightweight materials, grants a significant boost in power thanks to its high-flow trapezoidal shape and gives your bike a great sound without being excessively loud.  The muffler will help your engine make more power while reducing overall weight. The end result is an exhaust that will let your motorcycle reach its maximum potential!


  • Superbike technology and styling
  • Trapezoidal-shaped sleeve
  • Straight baffle for ample flow
  • Innovative end-cap
  • Stainless steel mid-pipe (applicable models)
  • Made in the USA

Awsome great looking I bought this product a month ago. So far I love it! It looks amazing and sounds just as good as it looks. I had bought the carbon fiber one manly for looks. At first I was hesitate about buying this product even after watching several videos on it. In the videos they sounded dual but now that I got one they sound much deep and louder in person.

Quality construction, easy install, and the sound you want. Given that the CBR 300R is a single cylinder thumper, it has a unique sound all its own. However, one could easily say that the factory exhaust leaves a little something to be desired. A colleague described it as "an angry lawn mower." Yoshimura's R-77 definitely cures the Honda of such a description. Removal of the factory exhaust required a socket wrench and a box wrench. Two bolts and the factory slides off. You mate the exhaust hanger to the silicone gasket, slide it on the can, and slide the can into place. Screw in the hanger, and you're half way home. If you follow the factory instructions all the way, you will need to drill a small hole in the factory down pipe, in order to add the security bolt. Essential of you plan on really pushing your bile. However, if you're moving quickly, attaching and tightening the pipe clamp takes a socket wrench, and thats it. Total replacement time? maybe 45 minutes. If your dad has a killer set of tools, you can swap out. Once replaced, the Yoshimura exhaust has a more pronounced growl than the factory can. If you choose to remove the included baffle, it gets throatier. The Yoshimura is also lighter, and a lower profile. It definitely gets noticed when riding. Also, the Yoshimura smooths out the bike's engine at higher RPM. With the factory can, the bike can get some rattles around 6-7K RPM. With the Yoshimura, the CBR is smooth through the whole power band. April 20, 2016
Extremely Happy!! I was a little skeptic to purchase this muffler at first but I am very glad I did. The "cf" finish looks amazing, dropped about 10 pounds off the overall weight of the bike. The sound!!! Couldn't be happier, I get a nice deep sound instead of that horrible wailing noise. Shipping was extremely fast! March 1, 2016
Love it! Super love this slip on exhaust! It's easy to install and the sound of it is awesome. It is definitely lighter than the stock exhaust. It's a bit pricey but it's worth it though I still hope that yoshimura would lower their price a little :) Shipping was a little slow for me but I think it's just me super excited! Hehe! I think I harrassed Revzilla everyday to know the shipping status haha! But it's super worth the wait! My bike looks very cool with this added mod :) February 7, 2015
Way louder than stock & quiet core baffle doesn't help much. The fit & finish is excellent. Installed easily. Wiped it down with alcohol, then started motor. Man was it loud, so I installed the quiet core baffle. It was also very loud. Had I known it would be this loud I probably would not have bought it. It is an improvement in weight reduction and size. Much better looking too. January 5, 2015
Looks great sounds great CBR300 is the best sounding single after adding this muffler. A quiet growl at low RPMs and screams at 10,500 rpm. Will not fit the CBR250 without modification, the CBR300 head pipe is longer. December 22, 2014
It ain't a bad purchase Fast shipping, easy to install, looks great, wayyyy lighter then the orginal one. Only downside is it kinda makes your bike sound like a dirt bike with really high compression(but then again it is 300cc). But I've learned to kinda love it in a way haha I recommend it.

a worthwhile aftermarket choice I wasn't expecting any big hp gains, just wanted to ditch the heavy stock exhaust. Fit and finish are good and installation was a breeze. There was one curveball though. Yosh recommends drilling a small hole in the stock header to insert a supplied metal "bolt" that fits under the hose clamp to keep the can from rotating after everything is bolted together. It was a bit loud for my liking so I installed the supplied "silencer". It still has plenty of grunt, just not quite as tinny. Note: to install the silencer pull off the rubber bung on the exhaust tip to access the screw hole, insert the silencer, add a little lock-tight and screw together. Be careful when pushing back the rubber bung, mine pushed all of the way through. Thankfully the folks at Yosh sent me a new one along with a keychain. To sum it up, good fit and finish, easy to install, maybe gained a horse or two, but the biggest plus is the wight saving. You might be surprised at how heavy the stock can is. November 9, 2014
