So for those who's in the market for exhaust, you cant go wrong with either exhaust. Both are phenomenal products. BUT, if you want to make your M5 louder and meaner, i highly recommend you to get the Eisenmann

So you like the Eisenmann better because it is louder under *all* driving conditions? Was it equal to the Akra in any way? Did you try the Akra with constantly open valves (if it is possible to configure that way)
