Paul,
I don't know what engine you have, but I have a friend with a great 302 and his is so quiet that if he drives by at normal speed and you have your back turned all you hear is the gravel and wheel noise as the tires roll. On the other hand, mine is a tad noisy. When I start it, the neighbor's window falls down.
But they make baffels and other ways to quiten them down and really not lose a lot of power.
Ron
