The dawning of insight is a beautiful thing - especially for folks who tend toward authoritarian statism
Glad youre coming around

There’s a few subtle differences, for example the Sparks seems to be using a narrowing at the can to create a little bit of back pressure in the system, that’s needed to not lose some lower rpm power, and they seemed to have balanced that well. Meaning just enough back pressure to keep the midrange solid while opening up the top a bit. Sparks also used better materials, specifically the Inconel headers.
The Akra WSBK may have a slight restriction in there somewhere too for the same reasons but they did it elsewhere in the system if they did. Maybe in the headers?
The Sparks was designed by a bunch of Italian engineering graduate students as a school project, who had access to some of the most advanced modeling software.
Having said all that, I suspects there’s very little difference between the two. Physics are the same for everybody, which is why all new cars are starting to look alike, airflow works the same regardless of manufacturer, so if everybody is optimizing it a lot of stuff starts to look the same.
Well that system has been used in WSBK for 1 season and only because they stepped up as a sponsor (Go Eleven). When Chaz was on the bike it was Akra because it was a factory bike. They must have handed those student the Akra exhaust and said copy this, change like 2 small things
Rick, the EV thing is always going to be there but there are simply not enough minerals to make the transition. Seriously the numbers are mind boggling in terms of whats required in raw materials. Also the amount of Co2 saved is not that much over the life of a vehicle.
Synthetic fuels look very promising as well, with existing vehicles being able to use them and infrastructure already in place, etc. I can see the argument for zero-emission in cities to help with air quality but it’s not zero-emission when at least 60% of the electricity is produced by gas, etc.
Where did the money cone from for this content....
Maybe, I dunno, doesn’t really affect me though, I got a good exhaust, I don’t really care what badge is on it, and it’s not like they copied it in some Chinese factory and used cheap materials and ...... welds to make it, they upgraded the materials and the welds look great.
And I didn’t have to jump through hoops or know somebody who knows somebody to get it.
They are a good name anyway and it looks pretty awesome. Do you have a video of the sound from it somewhere? What’s the db level?
I do. Anyone know how to share a video?
I'm not sure the forum can do a video? Maybe upload to YouTube and share the link?
I’ve never uploaded anything to YouTube. Maybe I can send it to you?
Ducati must really want to get rid of its F20s and 21s. Blowing them out on fire sale! Seems like you have to shell out around £200k for one of these jobs (or half of what Steven spent on his bike… so far).
Would love to know what’s going on in the rear subframe. Is there is mass damper back there like the GP bike?
Since everyone asked so nicely. View attachment 48293
Many Mama Mia's
Stunning.
The visibility can't be very good out of that silver helmet you've got on the cabinet...
