I have a 2009 550i with Mtech kit and want to maybe add a CF lip to the front of the car. I have seen a few different ones and was wondering if you guys knew anyone that sold these parts and if the seller was a good company to work with. I am also thinking about buying a RPI exhaust for the car.. have any of you had this installed on your car? What do you think about the sound and power gain? is it worh it?

TIA
