I've been thinking about going the same route on the F90 M5 Comp I have on order but I think I'm going to wait and see how I feel about the Comp Exhaust, especially after reading your post.

Given the MPE will not be Akra, it will be another option worth exploring.

I agree that $8500 is getting up there .....
Be sure to give the Comp exhaust 2000 miles to break in. The water from the exhaust cycle inside the pipes coats the fiberglass matting and it gets louder. It’s not Akra loud, but it’s good enough to keep. Also keep in mind the M5 cabin is heavily insulated. I had to park my X5M with Akra beside my M5 with Comp and stand outside while my wife revved each one to compare. X5M gets a lot of exhaust sound (good thing) inside the cabin. M5 is quiet.
