The fact of the matter is most exhausts on the Z drone to some degree. Not a whole lot of sound deadening in these from the factory. Unless you mod the cats you'll probably not notice much change cruising at 60-70mph in 6th though.
So if we're talking "highway drone" with the Motordyne then no it isn't too noticeable, but around town cruising in anything lower than 6th gear between 2-3K you'll feel the throttle in your ears - HOWEVER, its totally worth it and not a nuisance because the sound is so, so sweet
