Hard to he 100% as I don't know which engine you have, but it's probably a valved exhaust and is completely normal

Hi my car is 2018 b9 petrol s4.
And thanks for your reply.

100% normal on an S4, it's model related so you would have benefitted from informing the forum in the first place ;-)

Yes, it's normal. Two valves on the S4 - one is behind the backbox on the right, the other is before it on the left.

This means three, two or one tip could be "closed". When idling, I think three are usually closed.

Much appreciated .

Pop the car in Dynamic ADS and it’ll open all up!

I’ve always hated how it does that in the winter you see it just from one tip, which looks *****! (And I don’t want anyone thinking I’ve got one of those S4s with the fake exhausts )

Or just unplug them
