Fabspeed does make a full exhaust kit for the boxster. It comes in Two stages:
1. Headers with 1 cat per bank
2. Cat back exhaust with secondary cat delete (if you had them to begin with).
They are considered to be a pretty good company from what I've heard. Personal, if I was to buy a new exhaust I would go with fabspeed. They are, however, a bit pricey.
Hope this helps, here's there website:
