IMO it is more important to do the mids than the muffler... I primarily did the muffler, some months after doing the mids, to reduce the drone and for the looks.
HPA sell MadDad mids for around $700, although big back orders on them now.
So in your experience the Maddad mids did not help reduce drone? I thought they would be similar in that sense like the N55, almost everyone reported reduced or disappeared drone.
