Yoshimura R77 Race Slip-On Exhaust Honda CBR300R / CB300F 2015-2016
Great addition to my 300..
I think this pipe is a great addition to my bike.. It was a bit steep in cost but the finish and quality are high up there so I can't complain. I bought it so my bike would be louder and it sure is.. I feel more comfortable with people hearing me when I'm on the road. It came with a silencer but I have yet to really use it, It fits right in and helps with noise. I am happy that it made my 300 more enjoyable to ride since I can hear it roar as I get on the gas. On long rides I recommend some ear plugs but overall it looks great and fits the profile, and adds enough noise to make it "cool". Installation was easy as well.

Great looking exhaust
This yoshimura slip on makes a huge difference in appearance and weight. It's super easy to install, and the sound is much nicer than the stock exhaust. I wasn't able to hear my bike over the sound of leaf blowers before, so from a safety standpoint, it's definitely nice to be heard by cars finally.

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.

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!

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 :)

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.

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.
