Modern Buddy

Even though it's an early '08, my Buddy is still in very nice condition.

Except for the chrome exhaust finisher, which is rusty and pitted. According to the parts manual I have, it's not available as a separate part.

Or am I missing something?

It isn't, you'll have to pick it up secondhand. For the rust, you can try scrubbing at it will a wad of aluminum foil (harder than rust, softer than chrome). It won't take the pitting away, but it'll remove the rust.
