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?
