I got a Yosh RS-3 SS slip-on on my 06 600 Kat. I like it alot. Quiet at idol, loud enough when u get on it (WOT/high RPM's)

I've been very happy with my Yoshi RS-3 since I fitted it.

I'd recommend it to anyone who wants to give their bike a bit of aural character, without making it annoyingly noisy. The stock muffler really does make the poor thing sound like an appliance.
