Perfection.
I just purchased a 2018 Street Glide Special and my local harley dealer installs these pipes with some of thier new bikes. Once they fired up a bike with the S&S MK45 I knew I had to have a bike with those pipes. Perfect for touring. Idle has a deep but not annoyingly loud rumble to them. At cruising speeds they are calm and quite like I would want. But soon as you roll on the throttle they it brings the sound of your bike to life. A deep and very aggressive sound with the perfect amount of crackle once you let off the throttle. I was sold at first start up
