CARB Exemption Database Link Inside
 

I've spent the last few nights after buying my '05 S2k looking for CARB exempt parts to start my modding spree. I couldn't find a very authoritative site on which things are and are not exempt and I finally went to the source, CARB itself! Hopefully this will show up in search and be an easy reference for us CARB conscious s2k'ers.

And for headers:

Comptech:

DC Sports:
HHS5020, HHC5020 2000-2001 Honda S2000
HHC5020, HHS5020 HONDA 2000-2002 S2000, 2 L
HHC5020, HHS5020 2000-2003 HONDA S2000 2.0L

For some reason I can't find any catback systems on that website. It seems that the "Exhaust System / Exhaust Modification" category only includes headers. *shrug* This at least narrows down my choices for potential mods.
