Question for exhaust experts!

I have a 2014 550 and I purchased a M5 DTM diffuser ! I know this brings the exhaust closer to centre ! How much closer? And should I be buying an exhaust for a 550 or a M5 because of my diffuser choice?

Thanks!

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.

I believe the M5 is 76mm dia (about 3") and 550i is 70mm ( about 2.75").

You will want to buy a M5 exhaust.

Most 550i exhaust will not fit a M5 diffuser unless you modify it. It also won't look as good as a M5 exhaust.
