Volkswagen Golf mk6 R Valve open/close comparison

A quick video showing the difference between open or closed valve in the resonator of a golf mk6 R. Not the best way to measure sound (phone app) but an indication of the difference between open and closed valve.

How do you open ?

Hey Jean, if you have the stock catback you can disconnect the vacuum hose connected to the valve membrane, plug it off and the valve is open all the time. This is also called "the flapper mod"
