I've had several styles of mufflers (and straight pipes) and for the daily rider this muffler is a good mix of noise levels. At idle, the exhaust is just loaded enough to let you know it's there, yet doesn't cause excessive interior noise. When you give it a little throttle, it fills the air with a nice, audible growl, but that fades as you move. I had a camera on prior to installing this Delta Flow 50 series and couldn't speak to my wife without yelling at her at 75 mph with the cruise control
