Exhaust things

[TURBOTRONICS]

Iv been having a look around my new 03 s4 avant and iv found what look to be 2 actuators of turbos one on each tail piece
What are they for and should they move when revving the engine?

They open when you hit the sport button they are also prone to seizing up so get your WD40 out.

They give the exhaust a better/louder sound when open, some people cable tie them open because they don't open when the car is stopped or somehting similar.

I take it the manuals don't have a sport button so it must open after a certain rpm.
