What's the Best Stainless Steel Exhaust for standard PX200?

What’s the best Stainless Steel exhaust to upgrade to on a standard PX200. I’m quite happy to up the jet size but I can’t be bothered with getting into tuning the cylinder head etc.
I was thinking of a ScootRS tuned exhaust or a Scorpion? Has anyone got any views or experiences of these please.
Remember I want to leave the engine as standard, as I don’t have the time to be messing around with it, so please don’t go quoting Malossi and Polini at me!
Thanks in advance you your replies…if I get any!

…with a standard engine get an RZ. But I have to say that i don’t like standard engines with expansion exhausts. In case you can tollerate no stainless then go for a PM.

…forgot to mention, the cheaper the better!

Cheers,
which one, the EVO or the MK1. I forgot to mention that I want to keep my spare wheel
