X-Pipe effects on X5M worth or not?

[miguex@ecuprogram]

I just wanted to know how will the X-pipe affect on the X5M (for better sound or performance) after the stock has not it and akrapovic neither.

The only brand that comes with X-pipe is SuperSprint also custom ones.
The current F10 M5 stock exhaust comes with X pipe.... right?

I am undecided to keep the stock middle and change the mufflers only or install the x pipe + mufflers.

Akra does have x pipe and it does improve sound.
