I have an 06 550i and i was wondering what kind of performance mods should i put on it.
I might buy a sprint booster for it but not sure if yet. Also i want to increase few more hp I already have an meisterchaft exhaust. Any ideas ??

Honestly coming from someone who owns a 550, but there is really nothing to increase hp out of the car. On these if you don't go with a supercharger you wont get much yield of hp from any mods. The afe cold air intake actually causes heat soak and can cause some power loss. Others say the carbon filter delete does much more for the car than an actual intake does. And for the price dinan is not worth it in my opinion. Other than that sprint booster doesn't add hp but it definitely does decrease the throttle lag and makes your car feel more alive but def not more power. So performance wise these cars are a bit tapped out unlike the 535. Feel free to pm if you want to know what i have done and if any other mods are worth it. Don't get me wrong they're great cars, but not ideal for performance modding sadly enough .

Wow that sucks I have a 07 550i none sport look. So I guess all I can do is make it look better with bumpers mirrors wheels the self damping struts/springs and quad my exhaust. To me 360ish hp is cool with me.

So far I have:
Upgrade halo lights 10
Smoked side markers
Retro fit 2014 joystick illuminated shifter (www.bimmian.com)
M5 mech front bumper (www.umnitza.com)

Get sprintbooster v2 and you won't need any perf mod.
