Question on M550i Rear CF Diffuser Installation
I’m getting ready to install the BMW OEM rear bumper cover and carbon fiber rear diffuser on my 2019 M550i. I’m keeping the factory exhaust and tips. For those that have done this...
Does the Exhaust System Support Adapter Cover shown below (#51122433183) that comes with the new bumper cover need to be installed? Or, since I have an M550i, can I just install the new bumper cover and diffuser using the current exhaust system support adapter cover? Hoping I don’t need to replace the exhaust system support adapter cover because that looks like it requires a rear bumper removal. Thanks! Last edited by HomeIn2; 01-05-2019 at 03:59 PM.. |

I would ask a tech at the dealer on that one

I did not use the new Exhaust System Support Adapter Cover that came with my OEM CF diffuser. I just installed the diffuser on the Exhaust System Support Adapter Cover that came with my factory M550l exhaust.

Did you have to do any modding such as drilling extra mounting screw holes or similar ? What I find confusing is that the replacement M performance bumper cover (51192412410 ) which is required for the diffuser installation is specific to M550i only. Now, if the stock Exhaust Support Adapter of 550i allows replacement bumper cover + diffuser installation, why does the M550i specific (51192412410) kit include a replacement Exhaust Support Adapter ?

THAT, is a question for the ages! Perhaps it’s needed for the M-Perf. exhaust install on other G30 models. |
