Re: X-Pipe or alternative to complement new rear boxes?
An X pipe will definitely make it louder, but since your boxes are custom, there is no way for us to predict whether they will be "too" loud, let alone whether they will be illegally so (I have no idea what the noise requirements are in your area). If you do a search, you can probably find some sound clips of X pipes combined with some of the popular exhausts such as Kelleners (supposed to be very loud compared to stock but I've not heard them with an X pipe), and Supersprints.

Future - F10 M5 with manual transmission?
"Is it the sounds that make a BMW a BMW? A BMW is designed to be heard, felt, experienced. So our engines sing. Our steering talks back. And we insist on offering manual transmissions in nearly all our models for drivers who crave them. The result is an almost telepathic oneness with the car. Just as surely as you can hear a BMW, a BMW hears you."
