The sound is amazing.

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.

The Gibson system was very straight forward and easy to install. Better yet it sounds fanatic !! Deep throated growl when you get on the gas. The only suggestion I would make , would be to include the 2 nuts for the bolt on flange as my old ones snapped off. Other than that very pleased!!
