Thanks Sherb. I personally dont like too loud exhausts for m5 as its a sport/luxury car. Those Eisenmann exhaust on the gray m5 were loud man. I would get into trouble with my neighbours!! Lol :Thumbdown:Those systems actually sounded pretty nice. Throaty, not overly loud or ear piercing. Didn't appear to be raspy. Liked them. Think I was actually parked about 4 cars down so I got to hear them a few times.
