OEM 550i F10 M Sport takeoff exhaust. This is the complete OEM exhaust from a 2011 550i F10. At first decided to mode the original exhaust to look like the M5F10 quad rounded tips look. Plan change to retrofit the rear bumper to the OEM M5 F10 so I ended up purchashing the M5 OEM F10 exhaust to complete the job. This 550i F10 OEM exhaust has been moded with quad rounded Active Autowerke exhaust tips. It will fit the current OEM 550 rear diffuser and diminish the look of the lexus look alike square exhaust tips. Everything is original OEM from the exhaust manifold downstream to the exhaust tipswith exception you will no longer have the square tips but rather a quad round tips. Here is your solution if you are looking for a OEM look replacement without spending the big bucks. PM me for more info. Asking $1200
