These exhausts are not final yet- they go through an elaborate tuning process for sound resonance and the are evaluated.
I hope you're right and that they continue tuning the exhaust note all the way up to production. If I'm going to drop nearly $80,000 on a car, I don't want it sound like the fartbox in that video.
