I understand that you just wanted E93 owners with the Akra axle back, but I have the Active Auto resonated x-pipe with high flow cats mated to the Akra axle back. It is a perfect sound at all RPM's. It doesn't matter if the top is up or down, it sounds great. The wife drives the car also, and she is not upset with the sound. I can only guess the Akra axle back setup will be a little calm. Hope this helps.

cold start. warm idle. in-town driving. freeway cruising. WOT.
