Problem is "drone" to one is "no drone" to another. Peoples hearing is notoriously different
OK UPDATE.

So I took her for a long drive yesterday and really payed attention to the sound up at the higher speeds. Around 80mph, in order to consistently cruise at that speed you have to have a little bit of gas and the RPM will be around 3k. Well there is a slight drone around 80mph, good news... it's really not that bad. Certainly not deafening or really loud. But you do hear a rumble. It's aftermarket and def louder so I guess that's one thing you have to take with a grain of salt.

By the way, nice jet black e92 in your pics
Thanks John! Good luck with the install, it will def be louder than it was!

Personally I don't understand the point in coating the muffler, can anyone explain?
