[Video] Leveled-up AC Schnitzer Exhaust for the BMW M550i

Take a listen to the AC Schnitzer homologated silencer for BMW 550i. Listen to the difference AC Schnitzer vs. standard. It has surely leveled-up the growl. While the standard M550i sounds good when taken up to about 8/10, the AC Schnitzer alternative does a better job all throughout the rev range. Furthermore, it seems like their quad-tip exhaust style looks better than the trapezoidal stock versions. What do you guys think?
