Same here.. have had the N55 mids on for about 4 months and the sound just gets better after every km..

Nice and deep without the high pitched rasp of the Maddads or Berks..

And get about 7 kws or 10HP gains at the wheels from this mod..

Very easy to do your self.. Once the car is jacked up and secure, shouldn't take you more than 20 mins to R&R mids..
