hi guys, my brother has just bought a new dsg s3, extremeley nice. hes not been out of it all day! ifor those who own an s3, the exhaust burst sound when the car changes up a gear sounds so nice. i was just wondering is it a valve in the exhaust or something? and also is it possible to get an exhaust for the 2.0 tdi dsg which will produce the same noise? cheers guys.
