2) Since CA doesn't sniff anymore on certain model years (including my 2000 S), that 2nd cat's weren't an issue. And I have a guy that is WAY to lazy to get under my car to check, so I'm good with visual
3) This got me to thinking about headers. And since my boxster is mainly a track car, I'm thinking of putting them on (research tells me they DO make a difference on our cars).
Question is - for those that have headers, and especially those that have headers in CA -
1) What all is involved in KEEPING the primary cats and O2 sensors with headers? Is it a big project, or pretty much plug and play?
2) Do you feel the performance improvement and potential new life of crime is worth it?
Thanks for your input!!

I don't have an answer to your question but can you elaborate more on item 2?
My 02 is due for registration and it states it needs a smog certificate.
