Cant say what works *best* but my renegade can (baffled) is quite good on the skorpion.
I think it was pretty similar externally to my (unbaffled) Renegade can on my SRX620, just much more civilised.
I think you could use use a number of generic ones, I'd be most concerned about getting a link pipe to mate the headers and can re. diameters and final position of the can.
Not really sure whats available off-the-shelf, mine is a bit of a lash-up, and not entirely gas-tight, but just about good enough.
Cheers. Maybe more info on MZOG (yahoo) or MZ riders, or mzskorpion.net??
