An F30 N55 Downpipe is regarded as the best hardware upgrade to get the most power from your N55 powered F3X BMW.  The stock N55 downpipe comes from the factory with a catalyst that severely restricts exhaust flow.  Upgrading your downpipe unlocks power, improves turbo spool, allows you to run stage 2+ tuning, and increases the exhaust note of your N55 powered BMW all at once.  An N55 downpipe upgrade is the first hardware upgrade every N55 owner should invest in.
