Can anyone explain or link me more information on how the N55 for the E9X platform differs compared to the new F30 generation? Doing some searches brings up limited information both here and on the F30post N55 thread. It seems like the main differences are the tuning, intake and downpipe (to be general about things). I'm trying to gauge whether my current 2011 E92 N55 is worth keeping and doing up for daily driving/very regular track use or part out what I have so far and get something else.
