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.
