Yoshimura Alpha Exhaust Install on 2019 Kawasaki Ninja ZX-6R 636

@@eastcoastish do you have the decibel reading for this?

[@SpyvsSpy-yl9ip]

I've got the same bike, same color and exhaust. I'll never sell it. Such an amazing 636cc machine. The only other bike I want is a s1000rr and a Ducati Monster or Diavel. Anyways, the Yoshimura is one hell of a pipe. I looked at all of them...Graves, M4 Street Slayer, Akrapovic, Austin Racing, SC Project, two brothers etc... but I wanted a classic Japanese exhaust for this beast of a bike. It didn't turn as gold/bronze as I had hoped but it still looks great after 1400 miles with this exhaust. The carbon fiber is excellent quality and finish. The heat hasn't warped it at all. All in all a very fine exhaust system, muffler and mid pipe. I recommend a ServoBuddy so you can pull the servo motor and cables out of the seat area, it's unnecessary and the included servo mod is kind of janky

[@screennamenottaken2]

Spy vs. Spy Just curious, in your experience how common would you say warping/degrading issues are for exhaust cans with carbon fiber? I have a 2019 zx6r also but the base model all black bike. I’ve been considering a few different exhausts and pretty much have it narrowed down to either this Yoshi exhaust or the Austin Racing GP2, probably in titanium/carbon fiber. I emailed them a few times with some questions and asked if that was an issue with their carbon options. They said the GP2 is just a carbon fiber sleeve over titanium and has no issues with heat.

[@SpyvsSpy-yl9ip]

​@@screennamenottaken2 The carbon fiber is very high quality. The best i've seen on an exhaust. Very durable and it has a nice tough gloss finish. I also looked at many other exhausts but I am very happy I chose the Yoshimura. Its very solid and high quality, its worth the price. In my opinion it's also the best sounding exhaust i've heard on the 2019 636

[@zagazagas]

That Yoshi Exhaust sound note is the best

Great video but to give you some extra room and less dead weight you can remove the entire servo unit. All you need to order is a very tiny part called a ServoBuddy that tricks the FI system in thinking a servo exist.

[@eastcoastish]

[@JimmyFaev]

great video, helped me out alot... I installed the Alpha exhaust today on my 2020 zx6r... its so much louder than i thought! (maybe too loud, i might install the baffle) at some point the servo swiveled, so the mechnism wasnt able to turn.. which triggered the check engine light... get a servo buddy!

I love the way mine sounds, I have the exact bike and put the same exhaust on. Fell in love with it instantly especially on the highway, good video bro hope you enjoyed yours.

[@R62009PA]

I didn't scroll through all the comments but I wanted to offer a bit of info. The muffler installs behind the rear peg mount, not in front of it. it looks as though you installed it on the outside of the passenger peg instead of behind it. Just an FYI to the viewers. I can say even after installation of the servo plates mine threw a code anyway. Also just an FYI. I ordered a servo buddy. Otherwise, great video and thank you for posting!

[@eastcoastish]

Congrats on the bike! You installed the mechanism that tricks the servo to think the stock exhaust butterfly valve is still there? Have you put some miles on the bike to see if the code clears? If you did install correctly and have put some miles on the bike, easiest solution is to throw a servo buddy on there, I did a video on that too: kzbin.info/www/bejne/a4naiWiVrM6jhdk good luck!

[@scienceofone]

I have the same exact bike, which model Yoshimura is this, sorry but I don't know much about it. Also I looked on ebay but it only shows the muffler, whereas you remove both sections, the muffler and the pipe under the bike, so I'm a little confused as to what I need to buy exactly. I loved your video though as I wanna do the exact same thing. Also is changing the servo a must?

[@eastcoastish]

You can buy it directly from Yoshimura: www.yoshimura-rd.com/products/kawasaki-zx-6r-2019-street-series-exhaust-14642cp520 This is the "three-quarter" exhaust as opposed to the "slip-on" which is just the muffler portion. You must either use the servo bracket that comes in the Yoshimura kit, or do the Servo Buddy which was much easier and cleaner: kzbin.info/www/bejne/a4naiWiVrM6jhdk

[@jezreelrobin7596]

[@eastcoastish]

[@xnick184298x]

Did you have to do anything else to the bike (ie tune it) following install?

[@eastcoastish]

Yes, I installed a Power Commander V and had it dyno tuned. It's not required but definitely gets the most out of the exhaust and helps shape the power curve.

[@shawnkurtisTV]

Question: I’m installing a M4 GP19 slip-on onto my 2021 ZX-6r and I’ll be eliminating the cat-converter along with adding the servo buddy. With that being said, is a flash needed? Does it ruin the bike in any way if I go without doing this? Lmk! Appreciate it!

[@eastcoastish]

If all you're doing is adding the exhaust, you don't need a flash or Power Commander V or something similar but it will help get the most out of your exhaust. You won't do any damage though - exhaust alone won't lean out the mixture enough to make a difference.

[@tommysbk2919]
