I've been looking around for a while to find some 200 cell cat headers for my Boxster. Since it is a weekend cruiser as well as a track car, I still need to pass emissions here in Phoenix AZ so I would think that the 200 cell cat headers should be ok for me since I have already installed secondary bypass pipes. I'm also looking for an extra few HP this would give me on the track.

I emailed TopSpeed and they don't have anything for my car. It seems as though there are 2 options: Fabspeed (expensive) and NHP. The other option is to just dedicate it to the track and put straight headers, but how big of a job is it to switch between stock and track headers? Is that something that is practical?
