Tested on an N63-powered 2012 550i GT xDrive with a Stage 2 tune, the addition of ARM’s 3" Downpipes and Cold Air Intake yielded +48whp and +43wtq, raising output to 460awhp and 525awtq. The catted version maintains nearly identical gains compared to the catless setup, while offering the benefits of a catted exhaust system.
