Hi Guys
I called BMW Hong Kong and left a message about my quiet car and no answer yet
does anyone have any idea how I can get more noise from the unit?
is it possible to do some tweaks to increase its output or something?
I wonder if I can swap a M5 unit in for better sound(okay its sad but I would), but since they have different rpm I wonder what would happen

I am looking to drop in an K&N to see if it adds any noise (it usually does although minimal), and I am thinking if I need to get a full exhaust system instead of just the muffler this time...
