I have done some searching, and I "think" I have found the information that I am looking for, and I wanted to run it by here and see what everybody thought would be the best brands/parts/etc...

This is for a 2000 Boxster S

Exhaust parts:
Headers
---with sport cats, so no CEL. Are these $$$?
---without sport cats, to solve CEL ROW tune or spacers for the secondary Cat efficiency monitoring O2 sensors.
Benefit: freer flowing exhaust and more HP
Downside: Possible loss of low end torque?

Secondary cats:
---Remove with Cat bypass pipes, save a lot of weight and freer flowing exhaust for HP Gain?
---Leave on

Catback Exhaust
---Leave stock on
---Replace with an aftermarket system, lighter but possible drone, more power due to weight saving?
---Drill out the stock exhaust for the DIY Sport Exhaust Mod, better sound?

Are these the main components of the exhaust system that can be replaced?

Can you do just one at a time here and there as you save money, or is it better to do them all at once?

If you could do just one, which one would be the best? Best for power, best for sound, or best for ???

This is a new area for me so apologies for the simple questions. I think headers and secondary cat delete might be the first ones for me to tackle as I think one of my header cats is going bad, and I don't want to get any drone from a catback system, and I am happy with the current sound. Does that sound like a good approach?

Thanks
