Jardine exhausts on 2001 GS500 (non F)?

[TurkeyChicken]

The jardine site lists them as F model exhausts.  Is there any reason they wouldn't fit on a non F model bike?

Also, what kind of added performance (if any) could one expect from a new exhaust and rejet?  Right now  my bike doesn't have any mods to it.

It will fit fine.  Performance gains are minimal but what a good sound.
