My E46 has a terrible Drone FROM an EISENMANN exhaust!!
The metallic reverberation in the cabin is horrible.. Three layers of Dynamat extreme in the trunk and still no relief..
I am finaly switching to the OEM performance muffler as the drone is causing me headaches (I already have some hearing loss from Iraq/Afghan/Panama...) So I think it just has to do with individual CAR harmonics.. Not every Eisenmann exhaust causes Drone, so not every 1M will have it either..
