Help! M5 Exhaust On Mod 550i Diffuser

I want to get m5 exhaust muffler on my 2011 550. put I did a mod diffuser, so I don't know if the m5 stock mufflers will fit nicely on my new diffuser.

If your pic shows the OEM Msport mufflers in their original location, then its an easy yes, they will fit since they use the same hangers that the stock M sport muffler uses. Some minor tweaking of the quad tips are sure to be done, to your taste, but even then its no big deal since they're slip on and can be adjusted with a tap of a rubber mallet.
Now if you're thinking after market tips, 3 1/2 or even 4", then that's another challenge.

Yes they are but when you go to install your M5 muffler the shop with align it for you to fit your diffuser.

If you plan on using the complete piping then you'll have some issues but it can be modified to fit.

Visually, they appear more inward and that was my assumption. Could be just an illusion with the factory M5 facia unique styling but as I and many other have found out, the M5 and M6 muffler mounts right up and will exit the standard MSport diffuser. Maybe we're just lucky and you might encounter a few nits but, having been under the car myself during the install, I can't see anything that a good muffler guy can fix with a simple tweak.
