2015 Porsche 991 GT3 RS exhaust sound

I have filmed the all-new 2015 Porsche 911 991 GT3 RS starting up it's 4.0 litre flat-six engine multiple times, revving and then accelerating. This is actually the very first 991 GT3 RS I see on the road and I have to say that it looks amazing in person >> http://www.youtube.com/watch?v=xA9Jm7_jNz8
