As I promised a few weeks ago I have uploaded a small video of my S3 with the new exhaust settings. Before I had a decated & resonated and now is decated an no resonated. With this set up the car is extremely loud and inside you can feel some drone...an inconvenient for long trips but nevertheless is a lovely noise when you want to enjoy driving along twisty roads. I wasn't expecting such a huge difference between both settings, I think that the intermediate silencer is much more restrictive than the last one.
Here is the vid.
