Yoshimura R77 Race Exhaust System Kawasaki Ninja 300 2013-2014
She's a beauty!
I bought this exhaust because I need louder pipes and the reviews on this thing we're outstanding. It difficult comparing the sounds of the stock pipes and these on YouTube so I was a little hesitant before buying the system, but boy... I'm glad I did! It sounds amazing, it makes me have the chills sometimes. The install was a little painful at first since it was my first time installing a full system exhaust on a motorcycle. I recommend watching YouTube videos of people who already installed this type of exhaust and install everything LOOSE so everything will fit correctly. Overall, it was a great purchase, pricey but you get what you pay for obviously.

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.

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.

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.

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!

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.

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!

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.
