installing heimholtz chambers off the piping going into the mufflers is the only way to kill drone. Resonators will just change the tone. I just deal w/ it, and drive around it.

Been there done that. Finding
Te right frequency to cancel out is very difficult without proper equipment. And no. A local mufler shop can't help you. Being said, the chambers will lower the drone but now eliminate it. (Just ask aa exhaust
Owners ). There are few catless setups which do not
Drone. Dinan is one of them. Change your mufflers for akra or Dinan and drone no more.
