Artemis,
I believe the Akra Slip-on with wireless doesn't get the EC approval here in Belgium (it's for the slip-on only)
Hereby an extract from the installation guide:

12. For optional Wireless kit: assemble the clamps and Valve Pipe onto the muffler’s inlet pipes, as shown (Figure 35, 36).
WARNING: use anti-seize copper paste on all clamps’ bolt and nut threads!
CAUTION: in case of combination of Slip-On and optional Wireless kit, the Akrapovič exhaust system EC type approval is not valid!
Is this correct? I really don't want any trouble with car control authorities in a few years...
I have the N55 mids too, but can't decide between Akra Slip-on + wireless and the Eisenmann Sport.
I really can't justify the extra price for the Akra, although I know it has the best quality.
