Wow. It did sound good.

It IS a nice sound, however:
-this clip from You Tube has been shown here before.
-my M Performance Klappenshall dämpfer has slightly better sound in Sport (legal) and much better sound in Track (illegal). Looks are also outstanding.
-video/soundclip from Russian car undergoing dynotest with Klappen on thread:"Has anyone installed Klappen....." here on X4 forum.
