Not sure on N55 pipes. A friend put them on his 1M and is very happy with them, but he intends to change the muffler too. Mine would be too loud with a muffler change + the MadDad's IMO. The build quality of the MD's is also VERY good.
His N55 mids actually gave 10kW more power on the dyno, but it was a different day and different conditions. I'd expect any of these mids would give similar power increases and make the car more responsive. I did the change for the sound.... cheap $700 for good sound vs. $5k for an Akra system.
