Tuners: any plans to develop a drone-free exhaust for 1M?

Just wondering if any tuners or exhaust specialists plan to develop a drone-free exhaust for the 1M, or some sort of bolt-on solution to eliminate the drone.

I'm already aware of the "n55" midpipe workaround, but I'm asking about something more purpose-built.

Thanks in advance.

more purpose build?
The Eisenmann Sport exhaust (incl. the midpipes) has no drone.

Lots of users reported that Evolve/Supersprint has no drone. I hope to say the same thing myself soon. Also just a Maddad/N55 mid swap eliminates or minimizes drone. There must be many other brands.

I wonder why would any producer bother to develop a product solely aiming to eliminate a minor irritation like drone while many existing ones already do this among other usual benefits of an aftermarket exhaust?

I have N55 mids with Akra slip-ons + wifi and no more drone. With valves closed it's a pleasure to cruise on the freeway! No noise whatsoever!
