Are we talking about the valve at the very end of the exhaust or is there another one somewhere else in the exhaust system?

On my X4 M40i, both exhaust pipes have gas coming out when in sport mode and idling. I do not have a video where I am sure I am in comfort mode, but I do think it is the case too.

When doing a cold start, the left one is closed. Opens up after a bit (like under a minute in normal weather, maybe longer in winter).

I love this exhaust. If the X5 m-sport exhaust sounds similar on the 40i i will be happy.

Honestly that sounds awful, the B58 sounds way better even on a bad day
