E63s PE louder than non-PE
Or am I completely off base and PE doesn’t use different mufflers and isn’t any louder, it just adds the ability to control volume?

There's a fair bit of difference as well between the drive modes with the flaps open. Being in Sport+ or Race mode will definitely increase the snap crackly pop volume.
If I remember correctly, even the non-PE is also valved; it is just not controllable by the driver.

Now my exhaust consist of a 200cell sport cat downpipe with straight mid and mostly a muffler bypass, it is proper loud now.
