You are my hero
F06msportmia !! Booty of your 6-ers looks bad-ass.
Any difference in sound? I know 640i GC do not have the flap that opens in sport mode like on 650/m6. Is that part of your new setup? I'd leave it open all the time anyway, LOL
Now I need to talk to my mechanic and hope he doesn't charge me too much
