My long Akra is standard and is a bit marmite to some folks. Beavis just got a short Arrow for his and it looks minted in photos but even better in the flesh. Yoshis always remind me of the swords in the Kill Bill movies, Japanese engineering beyond what is required and sooooo beautiful.
Any quality exhaust will do the job Con, its personal preference rather than extra performance, although I'm sure I know which one Uma Thurman would choose!!
Keep us posted on the mods and pictures please.
