One really cold morning last week I had my S3 idling on the drive while it defrosted itself and I couldn't help notice that the condensation/exhaust fumes only seemed to come from the inside pipe of each pair.
I got to thinking that maybe this was because only one pipe in each quad pair is actually connected to the silencer box and that maybe the outer one in each case is only for show!
Since I wasn't able to investigate this apparent anomaly further at the time, I wonder if anybody has any definitive information on this issue?
