This thread shows the difference between the 550i diffuser and the M5's. However, the car is a 535i with a Remus exhaust. I'm assuming the placement is very similar though.

Yeah, they are not quite center using the M5 diffuser......What is the difference in the tube diameter? from 550 to M5.....If I order a M5 exhaust over a 550 exhaust I will probably have to reduce....Because from reading it seems the M5 Tube are 3" and the 550 is smaller but I'm not sure by how much.
