Firing on 5 Cylinders

My buddy picked me up last night in this Audi TT RS. Now I'm not usually a fan of bog standard cars but this is by far one of my favourite production cars right now. The turbo torque is amazing, it pulls effortlessly and that 5 cylinder howl is to die for.

This particular model has the standard exhaust system. When I was standing outside the car and sport mode was selected you could hear the valve in the exhaust open. I am interested to see how loud the Audi Sport system is as this wasn't exactly quiet. Here are some quick pics and a small video.
