I'm not sure. I haven't heard maddads in person, but I can't imagine there's a huge difference in loudness compared to the n55. I actually think I could tolerate a bit louder, but I'm very happy with the way this setup works. It's almost as quiet as it was at regular revs and cruising speeds, but it always has a more characteristic growl. Then, you open it up, and it reminds you what you have under the bonnet and below your butt.
