Hi all I'm looking at putting the r400s on my wrx, I have had the other r400 on my wrx in the past but the drone was so annoying I sold it and went back to stock, my question is has anyone had the quiter r400s on their wrx how much quieter is it than the normal r400 and do you get any drone from the r400s....loved the note and loudness of the normal r400 put out but hated the drone.
