I've also heard that exhaust in person and it just sounds mean as hell. The video picks up the high pitched F1 tone that it has to it, but that exhaust also has such a deep, ballsy sound to it in person that just sounds amazing.
Yes, I wish my car sounded like that, but I guess if you have never heard it in person than you might think that the sound is all rasp. That's really not the case though.
