My car is the car with the Euro Plate on it and the stock exhaust in the video. I just got the RPi Full GT Exhaust on my M5 yesterday. I am going to be posting a full written review soon, and then a full on RPi GT Exhaust video/commercial. The video will take a long time though as I am planning on taking my time with production for it.
I will say though, that having the RPi Exhaust on the M5 or any or other aftermarket exhaust is a MUST for the F10 M5. It just sounds SO much better!
