Yoshimura R-77 Exhaust System Kawasaki Ninja 300 2013

The R-77 is a perfect match for the Ninja 300. Its styling and internal dynamics complement this new bike exceptionally well. Not only does the R-77 enhance the aggressive styling, it provides an ample boost in horsepower and torque from mid-to-peak RPMs, just where you need it.

Improving styling and performance was not our only goal. This system also significantly reduced weight over the stock system, resulting in better handling, weight distribution, and fuel economy. Tearing up track has never been so much fun.

Full System includes R-77 muffler, stainless steel header and tail-pipe, low-volume insert, installation hardware, and detailed step-by-step instructions.

NOTE: Please check local laws before purchasing a Yoshimura Exhaust. Some modifications may be prohibited in some states.


This Product Fits:
Ninja 300 2013, 2014

This product is the most bass sound produced for Ninja 300 This is my first racing exhaust that I have with my first beginner sportsbike, the Kawasaki Ninja 250FI. The real thing in person looks so great, no pictures can justify the beauty of this excellent finished carbon fiber exhaust. The sound is not that loud, but it has a very elegance sound. It produces much bass for Ninja250FI and I uploaded a video in Youtube, recorded with Canon EOS 7D. You may lookup, Yoshimura R77 USA Ninja250FI by Denss2nd in Youtube. December 7, 2014
Very good choice for full exhaust First, the good: This full exhaust looks great (I got the carbon version), sounds amazing, and performs. On the ninja 300 you can expect a gain of about 5hp (with a flash or power commander) at the rear wheel. The sound is throaty down low, and screams up high in the rpm range. It was too loud for me without the baffle, but with it installed (it comes with the exhaust), it's the prefect blend of loudness and subtlety. Install was easy if you're at all mechanically inclined (much easier than the power commander). IMO this is the best looking exhaust available for the 300, besides the discontinued Leo Vince GP Corsa. Now for the not-so-good: The finish on the endcap is VERY fragile. If you leave it exposed to the sun, it will start to yellow within a month or two (even though the body of the muffler remains brand new looking). I recommend covering your bike (or at least the muffler) during prolonged parking in the sun. Also, I was expecting better quality welds for such an expensive product, however it does seem plenty sturdy and I haven't had any problems. Overall, this is a great exhaust system, and probably the best option if your goal is to use in conjunction with a piggyback fuel management system for gains in hp. If the endcap had the same quality finish as the muffler body, OR if it were about $100 cheaper, I'd give it 5 stars. I expected slightly better quality for the price, but I don't regret my decision to buy it and I would recommend it to a friend in a heartbeat. October 20, 2014
LOUD!! it was kind of a pain to put it on solo but it paid off. the new system is much louder then the stock setup and a lot more kick in the lower ranger. October 11, 2014
A must buy! Installed the full Yoshi system with carbon fiber can on my Ninja 300...it sounds A-M-A-Z-I-N-G. I paired this exhaust up with a PowerCommanderV, and the bike really moves. There is a huge difference in mid-top end acceleration. The exhaust system weighs half, if not a third of the stock exhausts wight on a ninja 300. Great exhaust system, really happy with my purchase! September 2, 2014
Awesome sound. I just love the looks and the sound of this exhaust! Add it to a filter and ecu tune and you can feel a power difference. One of the best upgrades I've done. June 25, 2014
Yoshimura Rocks I was not surprised that the Yoshi system fit great but it sounds even better. My little Ninja 300 sounds more like a 750. Really great sound and I could notice a change in performance as well. I would recommend this system to anyone with a Ninja 300. Quality cannot be beat! May 5, 2014
An absolute must have for the Ninja 300!! Install was actually a breeze. Looks awesome, sounds like a whole different animal. Installed with a Power Commander Five and it makes a really big difference. Throttle response and increase in the power bands very noticeable. April 17, 2014
Great price for a full exhaust! I bought this exhaust because the stock exhaust on the ninja 300 is too quite that it's actually dangerous to lane split. The yoshimura full exhaust makes the bike sound so sexy. It's only a 300 but it sounds pretty mean. If you're considering this exhaust, you will not be disappointed. In terms of performance, you feel like you're stressing the engine a little less when you hit those high revs. When you consider the other options available for the ninja300 how can you not choose this beautiful exhaust, it compliments the the bike perfectly.

A shopper asked: Does it fit the 2014 ninja 300 abs model? Sep 24, 2013
Answer this · Send to friends Good question? Yes (3) No (1)
Daniel Z: I installed mine on a 2013 non-abs, however, I can't think of any part of the exhaust system that would even come close to the ABS moving parts.

If you want to verify, Yoshi is located in S. Cal. and can be reached at 1-800-634-9166.

I think you'll like the exhaust - the fit and finish is absolutely beautiful. The sound is... well... music.

A shopper asked: Thinking about purchasing this for my 300... 1. I have not much mechanical experience ( I can change a battery and I installed the seal cowl), is this easy enough to do myself? If I do purchase and install, does the bike need to be re-tuned, and is that something the shop could do? Mar 1, 2014
Answer this · Send to friends Good question? Yes (0) No (0)
Daniel Z: You should be able to do it yourself with no problems - just take your time and pay careful attention to the instructions.

A couple of hints;

You just need to remove the right side lower fairing.
Do not start tightening bolts until all the new components are attached.
Look carefully at the instructions for where the gold spacer on the rear bracket goes.
If you are using the baffle, install it in the muffler before you put the muffler on the bike.
If you can, borrow (or buy) a torque wrench for tightening down the 4 header bolts to the cylinders.

To get the most out of your Yoshi, you should probably have your ECU flashed. I used Flash-Tune ($100 on an exchange basis). The removal and installation is quite easy - about the same as installation of a new battery. The ECU sits in a rubber jacket right behind your battery.

The Yoshi / ECU combination is, IMO, very impressive.

Good luck!

Chip h: Yeah you have to flash tune your ecu or you can install a tuner kit like the powercommander 5 but dont worry its fairley simple just wire up the tuner after you find defalt map for r77. The headers were hardest part requires a little force maby mine were spaced tighter. You dont actually have to remove gas tank to install tuner i proped mine up with 2x4 and connected wires. its a stright foward install that im sure you can do. The fender elimator is actually harder in my opnion.

A S: You really don't need to have awesome mechanical skills. All you need to able to do is to remove lower side right fairing, remove and install literary 3 bolts. You will also need to flash your ECU (I did mine with flash tune) or get piggy back system like power commander V or juice box. This will increase your power gain and reduce the flat spot. All torque specs and everything else can be found in service manual. Mar 1, 2014

Alexander T: I bought this a few months ago for my 300. I had no experience previously besides changing oil, tires and what not. If you take your time I'm sure almost anyone could do it. Also I don't think it requires a tune but this is something you may want to discuss with a professional mechanic.

Hope that helps.. Btw te exhaust sounds amazing. Very clean but loud enough.

Chip h: If you dont tune your ecu you wont unlock the full potential of a full system. But yes you can install without tuning. You would be better off just getting a slip on if you dont plan on tuning Mar 2, 2014
Reply to Chip Good answer? Yes (0) No (0)
nicolas p: Install is surprisingly easy. Just take your time and make sure you don't lose any bolts (like I did) and you should get it all done in less than two hours. I had very little experience and it went very easy. I recommend you get a re-tune in order to get the maximum performance but it is not a necessity. Runs fine without. Depends on the shop if they can do it. You could also buy a fuel controller and do this yourself and this will also allow you to retune again if any more aftermarket parts are added. Mar 1, 2014

Cristian E asked: I'm thinking about purchasing this Yoshimura R-77 for my 300 Ninja SE. Going over the reviews, I see that the system is okay by itself, I also see that I should also get a Dyno PCV. Also, I read about Bazzaz commander, would both work with the r-77 or is the dyno made for the 300 and the Bazzaz for something else?? If both are the same from different brands, which one works better? Thanks for your info and opinions. Feb 23, 2015

Bridget M: Wish I had better info for you. I went the route of having my ECU re-flashed instead of the dyno. Good luck with your research, I have been happy with the full exhaust on my 300. Feb 23, 2015

A shopper asked: Does anyone know if there is a place on the header to put an O2 sensor from the PCV auto tuner? Or would I have to weld this new header? Thanks in advanced. Dec 19, 2013
Answer this · Send to friends Good question? Yes (0) No (0)
Daniel Z: No place for an O2 sensor on the one I installed on my 2013 Ninja 300.

In case it helps, I recall that there was a discussion of this issue in the Ninja 300 forums at kawasakininja300.

On a side-note, the R77 is a very nice upgrade for the 300.
