You can't hear a difference in the loudness in this video, but you can hear the difference in sound. In my opinion the green Chevy got much louder while the gray Chevy sounds a bit deeper. Either way both sound great and you can hear them all the way up and down the highway. They are 5.3 Liter LM7's.
