This axle back system is a little louder than stock. If you hit the throttle they sing good but not loud, when you gear down they have a great rumble, not a spit and pop, also they have no drone noise when you level out. These are exactly as advertised. I am a little old to have cop callers, the quality of the street series are top of the line. Easy install, I'm very pleased.
