Who wants to send me an unbeloved part

Hi all, new member. I've bought a 2014 HM 821SP and the PO took out the actual disc/plate/flapper from the servo shaft in the exhaust. I've combined some parts to form a cool exhaust but it is very loud as expected. I want to re-enable the flapper valve in the exhaust and I'm in the process of getting the right equipment and software definition to adjust the settings of how the flapper behaves myself. this way I can profit from the additional silencing it brings at low throttle conditions like highway cruise and idle/slow takeoff.

Now I'm able to measure the stuff and get one laser cut myself but I'm lazy. Did someone delete the servo or inactivate it and want to send/sell me their plate? I checked ETKA but it isn't a separate part that is sold. Here is a picture of the exhaust result and first gen hyper handguards install.

I think they mostly get destroyed when removing. You have to grind off the rivets that hold the plate, which might be salvaged. I think you have to cut the ends of the shaft that moves the butterfly, too.

But I think you'll find, after taking a cutting tool to something you don't want, probably not many that keep the pieces.
 
Anyone care to make a good picture of the plate fitted and maybe the exact diameter? Ultimately cool would be to take the muffler off and close the valve manually and start the bike to tell me if it makes a lot of difference open or closed without muffler... Because that's pretty much my exhaust setup lol
