Not sure how real the video is, judging by the distance the car is from the camera and the exhaust note when it's half way down the road.

with long tube headers & H pipe; it can easily be this loud. But you're right, can't be certain if the video is legit.

awesome sound though!

EDIT: I've posted that fantastic vid on the C63 forum to confirm if its real or not. Most Long Tube Header owners confirm its real and claim its much louder in real life
