Disconnecting Exhaust Motor Valve

Hi all, is it possible to simply unplug the exhaust valve connector on the V4 without it throwing a check engine light? I did this on my previous Panigales and never had an issue, but have read mixed reviews here. I'm not trying to mechanically disconnect anything. Simply want to unplug the electrical connector for the servo. Thanks for the help!

Curious if anyone will know that is happening. I've disconnected the connector that plugs into the the exhaust valve motor, but I can still hear it regulate when I turn the ignition on.

On my previous Panigales, once the exahust valve was disconnected, you no longer heard the motor regulate the valve when the ignition was turned on. Attached is a photo/pdf of the connector I removed. If there is no connection to the motor, how am I still hearing it regulate? I'm wondering if it's still working after being disconnected. haha

I have had no luck with mine and have the servo eliminator version 2. Light is still on and has been reset so I gave up and just deal with the light being on.

As for hearing the servo eliminator after disconnecting it is not possible so it must be something else you can hear

It disables the servo and engine light and you get a better map to run the slip on or full exhaust

It is like 300 bucks

yes you can remove the flapper valve but it'll throw and engine fault light on the dash. You can ignore that if you want, it's no big deal. I bought the Healtech ESE but it didn't work. The Termignoni T-800 works well for me.
