You can buy off the shelf X pipes, no need to fabricate one, search Ebay. You'll need to know the diameter of the OE exhaust and the distance between the 2 pipes. I was going to fit one of these on my E55 but never got round to it. They are supposed to make quite a difference.

as with many tuning items, the question rises why is an x-pipe not standard?

But from your site were you give sound vill be not same like with self made x pipe i think, look in this video http://www.youtube.com/watch?v=RKUrJBTPXUo 3d sound is with pipe like you show me from ebay, and at 35 sec listen this sound is with self made x-pipe, at 35 sec sound is so amazing , i afraid 1 thing, self made x-pipe will not restrict gas flow ? because from 1 pipe to other gases will smash each other
