Under cold start the car revs loud, and as expected, calms down and levels out after about half a minute. At that point I would have expected to see the valves closing.
Nothing.
While driving at constant RPM and shifting through the drive modes there is a noticeable difference in sound, which is even more noticeable with windows down (so not only ASD making silly noises, actual exhaust sound).
I'm a bit at a loss.
Anyone know of a fool-proof way of making valves open or close while standing so I can test if they are working properly?
Thx

Had the same issue (but not for me because I prefer that way) with the Remus catback after installing on my M2. Any movement of the exhaust flaps, always open in every driving mode also in Confort. Everything fitted in the perfect place and re-checked but nothing.
I will keep it so, I love having a little louder sound
