When you start, the butterfly opens (as the exhaust is not so loud at idle), when you rev it you'll see the the solenoid activate which closes the valve at higher revs to dampen the sound.

Basically it holds the butterfly in the pipe open and "tricks" the sensor into thinking its working normall so you dont get the warning light.
You can get a switchable one as well.

If you pick one up, email me and I will send an english version of how to install it

There is no function available with the SEPST to disable it. If you just remove it then you will get a code on the speedo. You need an eliminator plug that fits into the harness where you remove the valve motor.
