Phil if it is a real deep sound even at idle You most likely got the 40 series which is considered a louder deeper sound. The higher the number the quieter the flowmaster is. I got the super 40 which is louder than the 40 and idle is deep not loud but when you go hard You hear it good till You let off. On interstate I usually do not hear it much at all.
My twin pipes come over axle in stock area like yours but I had mine tucked up higher where You can barely see them if you bend over which is about where stock were. I kind of wish I had came out farther which I can go back and do so I can add chrome tips.
