It's a cool sound for a track car. The note of the V10 is mean as fuck. I like loud exhausts, I used to have a V8 chevy with straight pipes. I loved the sound it made, until I had to drive it everyday, then it just got REALLY annoying. Plus it's a cop magnet like none other.
To put that loud of an exhaust on a luxury performance car is retarded. But I guess some people want so desperately to draw attention to their car, they don't care.
