Haven't been able to hear the sound of this exhaust. Why wouldn't they let you hear the same thing
New Yoshimura Exhaust coming!!!
Tim,
Thanks for providing some feedback here and setting the record straight in a professional and courteous way... that certainly must not have been your initial reaction, so it's much appreciated.
As for the actual development ideas, is there any chance of y'all trying to do a design that maintains the stock location and exit for the exhaust? The Akrapovic design seems to be the best option for power (we don't have any official dyno data for the Arrow that I've seen as of yet) but it's not without it's problems. Namely, clearance for spools and the need to flip the axle nut around. The axle nut seems to be something others care more about, but clearance for spools is a very real issue that many have had problems with. I have to admit, I personally don't care at all for the undertail exhaust, and can't really fathom why there is a 1 to 2 exhaust on a small bore single. Getting some dyno data is going to be imperative to success as many of us supporting members here on the forum are strongly pushing the mantra:
"Show Us Your Dyno!"
Exhaust designs which fail to match the stock exhaust may be acceptable to some, but on a bike that only makes 39-40hp to start, even loosing 0.5hp isn't acceptable just for looks and sound.

The twin undertail from a racing perspective is very appealing as it reduces the chance of scrapping a very pricey piece of hardware from a simple lowside... this is the top system on my list! now if you can just squeeze some power out of the thing!

I like the under seat dual exhaust as well. Considering the ground and swing arm clearance I have with the Akra on my race bike the under seat design is much more practical.

Speaking from experience, putting an underseat system on a bike that wasn't designed with one can be tricky. There's only so much room under there that you can pirate and still allow full wheel travel. I suspect that Yosh will exercise all caution in this area.
Keep an eye on our website and social media.. When we are ready to release any information you will find it there first.
Regarding Dyno charts, Yoshimura will only provide Dyno information to customers who call or email the sales department. This keeps nonsense like dyno-drag racing to a minimum and prevents encouraging pointless arguments over who's is faster based on testing performed by different techs on different machines on different days.

Maybe its worth the wait! I'm sure its not road legal. But I don't care How do you get it in Cali if its not street legal?
