BMS doesn't make a downpipe for the 550i. AR design does, active autowerks too I believe.
Trying to get some first hand impression on the stage 1 tune from BMS plus a catted or Catless downpipe. Obviously it makes more power but I'm interested in the subjective impression and would ideally love to drive one :-)
