Yoshimura Alpha Works Race Exhaust System Kawasaki Z650 / Ninja 650

The Alpha Works Race Exhaust System features Yoshimura's Works finished headers and midpipe that take on a unique coloring after going through a heat cycle. This special finish treatment increases fatigue strength, scratch resistance and just looks cool.

The Alpha Race series is the result of Yoshimura's investments in technology, combining decades of hands on race experience with the latest in digital design capabilities. The unique Tri-Oval design of the muffler is especially striking from the rear, where the large-diameter carbon fiber end cap and well-integrated, draw-formed, slash-cut outlet can clearly be seen. But there's more to the Tri-Oval design than its cutting-edge appearance, along with improved lean-angle ground clearance, this shape allows better use of internal volume to produce the deep, distinct exhaust note Yoshimura is known for.

Features:

  • More aggressive sound profile
  • Beautiful shape resulting from Yoshimura's Tri-Oval design heritage
  • Unrivaled fit and finish thanks to improved production tolerances
  • Optimized for maximum airflow and ground clearance
  • Designed for durability and ease of service
  • Contemporary satin/matte finish
  • 8.7 lbs lighter than stock
  • Stainless steel headers and midpipe

Perfect for Ninja 650R 2017.
I received it on time and the packaging was good. It was a hassle to remove the foam thing though. Installing this only took 15minutes but removing the stock one is a mess. I didn't have necessary wrenches which made the installation very difficult. Finally I installed it and it was LOUD. It was 103db-110db when I measured it. I thought it was annoying and installed the “Sound Insert” (DB killer) that came with the exhaust. The insert reduced the sound by 10db as it claims and it now sounds as loud as a stock Harley. There is some mild performance gain without any fuel remapping and to my surprise, the mileage is good too (50mpg city).

Dang!
Just as I said in the title! Dang! I did a lot of shopping around before ending up purchasing this exhaust; I had so many questions as to whether or not it would require fuel re-mapping, sound and perform well, or even be easily installed. I must say, I am highly satisfied with this exhaust system.
Here are my biggest questions answered!:

Fuel re-map: Not required. Check out some youtube videos on the dyno test on this bad boy and you will see that very little tuning is required after installation. As soon as you get back on the bike you will feel a difference, and know that no re-mapping is needed!

Sound: Wow. After hearing the youtube videos and then hearing it in person, I can say that no video or audio recorder can do this exhaust justice. Just beware, without the DB Killer in, you will need hearing protection!

Installation: Very self intuitive, especially with the included instructions. You should be able to have the old exhaust dropped and this one in within the hour.

And finally,

Style: If you are looking for a sharp, clean edged exhaust then this system is for you! I always disliked how some systems poked out the side and back of a bike too far, but this one is neatly and cleanly tucked into the old ones spot. And the pipes get a nice golden color after a few rides.

Perfect sound!
I have to agree with other review. Exhaust sounds and fits amazing. Installation only took around an hour and most of that was letting old one cool off. I purchased full carbon and recommend to anyone looking for a great sounding exhaust system.

Sexy Sound and Performance
This system is extremely easy to install. It's more work to uninstall the stock muffler than to bolt this on.

The sound this muffler provides is gorgeous, elegant, grade-A ear porn. The sound in youtube videos is nothing like hearing it in person. A welcome surprise is that upon calling yoshi, the improved 6.5% hp and 3.1% torque numbers they stated were from bolting on this system bare with no fuel mapping (power commander) changes. This was important for me because the common wisdom is that "if you install a full system, you must re-map". I didn't fancy dropping even more on a fuel map system quite yet and am glad I can wait until I feel the need for it.

Lastly I was curious if the improved performance would be "felt". I can definitively say the increase in power is noticeable. It won't your bike into a FTL drive but it certainly gets a better punch and the growl it provides while doing so is icing on the cake.

Overall I'm very happy with the yoshi alpha works system and I know if I ever lust after more power I can bolt on a fuel map system and play with the performance more. If you've been on the fence or have been considering slip on vs full (works system) get the full. The added performance is worth the extra $$
