Reply to "Seeking feedback regarding new mufflers and their effect on EXHAUST DRONE"

In my (Mustang) experience, straight-through mufflers (ie Mangaflow) are less prone to droning while chambered mufflers (ie Flowmaster and I believe the Ansa's as well) are more prone. Also, the further you can move the muffler from the passenger cabin the better off you are. Modern cars intentionally moved the mufflers to the rear of the car rather than underneath the passengers.
