Did anyone know something about an Exhaust-Valve-eliminator??
remove exup valvle??
hi☺
What do you think about removing the exhaust valve?
in what help?
What affects?
if I remove it from the muffler that I would not touch, none of the 2 metal wires to avoid the fault light will simply remove it from the inside of the muffler and I put a wedge to fool the servo if the fin is acting.
regards ✌

The valve eliminator still doesn't exist. Patiently waiting on this.
you can remove the valve and just undo the cables from the servo and it should not throw any codes as the servo will continue to act as normal, only its not manipulating the valve, at least this is what i have read elsewhere and possibly about the previous 1X99,
as for the valve itself I am not sure how to get to it as I have not messed with the one on my bike as I am planning on making my own slipons this winter and don't care that the valve is there, but you should be able to rip/cut the valve out and replace it with a nut and bolt through the left over hole or what some did on the 1X99 was just drill the rivets out of the flapper piece and the arm that it was riveted to... but again i have not really looked into this exhaust..
But I would not undo the cables from the servo motor unless you have removed the valve as the valve is most likely spring closed and it would be closed at all times which is not good..
someone please correct me if I m wrong or misleading here..

Normaly the valve is open the whole time,closed only in a small section of Rpm.
At the 1299 it has sometimes happend,that the valvespring is not strong enough to keep the valve open...
You couldnt see an error in the display when the cables are taken away,but there is an errorcode in the controlmodul...

Removing the cables and keeping the valve in place will still throw an error code.
Don't know but my V4S threw an error code @ 2k miles w/ the ex valve servo... luckily got it into the shop same day and initially they couldn't figure it out but after some battery pulls apparently it cleared lol; took them like 2 hours 
Mine is still attached but no cables no hazard on the dash but unplug it and it does show a hazard symbol bottom rh side
so left it plugged till some one does an electrical disable

What’s the purpose of this ? To get the exhaust to stay open ? Is it a noise thing ? Or power ?
I think the main reason is to keep it from closing at a certain rpm range (the range where they test for noise pollution to certify it for the road, probably)What’s the purpose of this ? To get the exhaust to stay open ? Is it a noise thing ? Or power ?
You see a dip in power around the same area, I wonder if this valve is related.
Other people say its to maintain low end torque.
I wish we had some dyno data with it open vs closed.
Exup valve: What it does
starts at 8:4X
If you watch the video from what I can tell this exup valve seems to affect both noise and HP. If you watch the video from 8:40- until 18:00 it sorta gives you a mixed message from the dyno and then when the tech manually closes the exup with the wrench ..... this may be a great purchase at $50EU. I wonder if Ducati will use it as an excuse if anything fails on the bike exhaust or engine wise . Would love to hear any feedback or opinions .
The main question is, does the exup close at the top end where it would matter horsepower wise? Thats the only time you need the extra exhaust flow, when the bandwidth of the closed valve exceeds the flow needs of the motor. From what I've heard, the v4 only has the valve closed at the low end, near where they test exhaust emissions and not the spot where you need the extra flow of an open valve.

Got a Healtech exup valve motor eliminator this week and threw the motor in the bin, as having a custom exhaust it was only on to stop a warning light now more weight has gone!
