If you search the forums the majority of user feedback reports no drone, while there's a few that comment of a slight one. What does this mean then? You can never be sure until you hear one for yourself (personally Remus sounds very raspy to me on the Z4M). One should also consider what other kinds of mods the feedback provider had when they reported the droning.

This is a good price on a great product -- and if you don't end up liking the mufflers for whatever reason they are easy to remove due to the bolt-on design. You should be able to get your money back, or even a small profit, if you sell them slightly used after Stromung increases their prices.
