Yoshimura Exhaust Kit? What is it?

Hi KZ'rs. I have a Yoshimura exhaust kit that I am trying to identify. It is a complete system not just a slip-on. It says Yoshimura RS-3 stainless on the muffler tag. What I want to find out is, what bike exactly is it made to fit? The part # stamped in the header is ZX903RRH. The # stamped to the muffler and pipe is ZZ903RT. That makes it sound like a ZX-9 system, but how do I know for sure, and what years? Any help is good help. Thanks.

Here's a link to their application chart.

Looks like they have a forum there also.
