Yoshimura R77 Race Exhaust System Kawasaki Ninja 300 2013-2014
Easy Install, Great Sound
Installation is pretty easy. Be sure to leave the headers as loose as possible and everything will be easy to align. Installing the baffle once the exhaust is installed was somewhat challenging due to the limited view and space. If you're certain you'll be using the baffle, put it in before installing the exhaust.
It is much louder than stock exhaust for the ninja 300, but not excessively. Even at high RPMs the noise isn't a problem, at least with the baffle in. It's probably loud enough to be heard on the interstate now.
The added bonus is that feels a lot lighter than stock.

Got the full exhaust on my ninja 300. The absoulte only thing that needs to be said about it is:
YOU HAVE TO HEAR IT TO BELIEVE IT. YOU TUBE VIDEOS DO NOT DO ANY JUSTICE.
If you don't want to sound like a moped anymore buy this and you won't regret it at all.

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.
