Call it drone... call it exhaust note.
I can appreciate an advocate for informed purchases, Guy, but you have not driven with our exhaust. With that said, you're giving advice on a product with no experience of said product.
We're quite familiar with drone, and developed patent-pending technology (i.e. 180 Technology) to deal with it. The Raptor did not require it.
Further, 95-105hz is the actual drone range for a four stroke motor, not 40hz. 40hz is almost subsonic, which is not where resonant frequencies with the human ear come into play.
We record our product videos the way we do to be informative, and replicate driving tendencies everyone would inevitably experience. There's no doctoring, no music overlaid, just organic material with nothing to hide (on an otherwise factory configured vehicle).
