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!

Features:

  • 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

I ride a CB300F with factory exhaust, it is a very quit bike and I have had multiple cars pull out in front of me in curves because they didn't hear me coming. I hope that by adding this exhaust it will make me known better to traffic with a performance boost as icing on the cake.

after checking all the reviews on other exhaust system this one topped all the rest. price is a little high but for looks and performance its never to much.

thought I'd like it but too loud

I've previously owned several Yoshimura slip-ons and full systems. I think they are well-made and competitively priced.

I really like this exhaust but I live in CA which I believe is not legal on the streets? What can I do to make this legal :) any thoughts?
Evangeline G on Jan 27, 2015
BEST ANSWER: I know a lot of people in California who has alternative exhaust systems on there's and have not been caught or sited. However! That said. If California has smog requirements for motorcycles, Then it becomes a matter of Pay Your Money and Take Your Chances. Personally I would get it and put the Sound Baffle in so not make it too obvious. Also don't throw your factory exhaust away as it has the Cat. Converter in it. Just in case you have put it back on for smog testing if get my meaning. Also be advised Yoshimura has the exhaust header pipes with the Cat. Converter in it. That's another option to ponder. I hope this helped, Good Luck
If I get this for my CB300f, will it require fuel remapping?
skyler f on Dec 16, 2016
BEST ANSWER: It is not required, but I do recommend it if you want to take full advantage of the exhaust.

After the install, my 2016 CBR300R seemed to be running a little lean. I installed a fuel controller and got her dyno-tuned, and that solved the issue.
What is the actual decibel increase after installing the r77 slip on without the silencer? How does this compare to 2 brothers, scorpion, akroprovic, etc?
Ian K on Jul 26, 2015
BEST ANSWER: I don't know the actual decibel level but it is over 100db. It is quieter than most other aftermarket slip ons but still sounds much better than stock. I put the silencer in after about a month because there was a drone at highway speeds that was uncomfortable without ear plugs. Fit and finish is good and let's be honest, it is just a slip on for a single so hp gains are minimal. Hope that helps. 300 was a fun learner but it has since been traded in for the 600.
Will this fit a 2016 honda cbr300r?
A shopper on Jul 10, 2016
BEST ANSWER: Yes! I currently ride a 2016 CBR300R with a Yoshimura slip-on installed.
This install is very easy, and the directions are clear. All you will need is the correct size Allen key for the job. I recommend applying blue Loctite just to be safe!
Any good alternative that is not as loud?
A C on Jul 8, 2016
BEST ANSWER: Its loud but sounds amazing keep the silencer in
Does this product cause any issue with engine light coming on or issues with fuel that would require the engine management to be tuned?
A shopper on Feb 5, 2015
BEST ANSWER: There were no engine light issues. It will occasionally pop on deceleration but I don't know if any fuel management would really be necessary.
Hi there
I want to ask that can this be used on a 2014 cbr250r or I should get the ones design for cbr250r?
because all the slip-on for cbr250r is for 2011-2013 model, while mines is 2014 model
so just wanna to check, or both will work?
thx
A shopper on Nov 26, 2014
BEST ANSWER: Yes! The exhaust system is the same and will work. The 300's are the same frame and motor as the 250. Except the 300 has a reworked engine head and a new programed fuel module with new transmission gear ratios to take advantage of the 17% more horsepower. ( And it is FASTER )

I need to see a dyno graph and how heavy is this muffler?
A shopper on Oct 24, 2014
BEST ANSWER: The muffler is little less than 1/2 the weight of the factory muffler. Approximately 5.3 lbs. If your going to DYNO TUNE your bike with this muffle you need to have the full system and not the Slip On. Also you will need a different fuel module to be programed to get the performance out of the system which would be noticeable. This slip on by itself has some minimal increase when graphed only, Not When Riding. The R77 Slip On looks good and sounds greats, not to mention the easy install. Hope this helps................WBV
