Huge difference! Would highly recommend!
Been waiting for this to come back in stock and took only 2 days to get to my location, extremely fast shipping. Installed on my Z650
This was well worth the wait and price, with a before and after video you can tell the difference but a video is nothing compared to actually hearing it in person.
Now it has a deeper rumble and growl . Would highly recommend this product to others.
Thanks Yoshimura for this outstanding full system!

Amazing Sound
Installed this on my 2022 Kawasaki Ninja 650. I went with the carbon fiber muffler. The install was very easy and everything fit perfectly. The sound difference is unbelievable. Definitely get more power, especially in the lower gears. The stock exhaust is so quiet. This exhaust is loud! Very happy with my purchase. I would definitely recommend this exhaust.

Perfect Exhaust System out of the box
Tried a Kelkavic 8" shorty first, It was WAY too loud. ran it 2 days and pulled it off. Put the Yoshi Alpha Carbon Fiber on and knew it was a keeper. I used the DB killer that came with it because I wanted to see how quiet it was. It was perfect Loud when you get on it Quiet at cruise and didnt require remapping . Installation was easy but did have to supply the exhaust gaskets. Looks great Very light and gave the bike tons of low end it never had. It was noticeable right away. Without remapping you might get an occasional back fire but nothing more than the stock pipe produced. Its really a great system. Yoshimura has been at this a long time and it shows . I was riding dirt in the 1970s and they were out there.

Lighter, Harder & Louder....
Waiting for the new air filter & then getting it on the dyno. Less jerky throttle
in lower gears even without tune. Curious as to what hp/torque/performance gains will be seen after tuning.
