Hey guys, just picked up my new baby girl this past weekend. 07 550i SMG, first bmw I have ever owned. Joined the forums hoping to find good advice and inspiration ideas for ma king my girl faster.

 

Welcome. Not too many affordable way to make the 550i faster. Best things to do are remove the charcoal filter in your air box, put in a new high flow filter, intake scoop, exhaust or muffler delete and some lighter wheels will help. There is also the sprint booster that will help with throttle response. If you have a lot to spend you can get some headers, full exhaust or a super charger.

 

to the forum! Good luck with the new ride!
