The sound of a 991 Porsche 911 uncorked is a beautiful thing. It's even more intoxicating when it's converted to Carrera Cup form. Here, there are two of them, and they're battling for position at the Nordschleife.

Filmed during the third round of the Porsche Carrera Cup, this video shows Kevin Estre and Sean Edwards dueling at the back of the lead pack. The dogfight is intense, with each driver flat out, but always looking for weaknesses in the other.

The duo continues the battle for the better part of an entire lap before a mistake from one changes the order--but as with so many things in life, it's the journey to get there that is most meaningful.

Well, that and the sound.
