i cant seem to find a s13 obx header for the ka24de... are the s13 boys just ment to use the s14 one or what???

i know a s14 will fit and work, but you have to plus second o2 and egr and aiv wont match up or somehting..

s13 and s14 aftermarket headers are the same.

doesnt the s14 header have a second o2 bung near the cat???

No for s14's the only difference is that they are labelled racing headers, due to the fact thaty the OBD2 engines now use a collector. Second O2 bung comes after the CAT.

my hotshot header has a second O2 bung right before the cat....

Wrong..... All the headers were designed for s13 use.
First port is for the EGR. Second port fits the AIV for OBD1 s13, or for the first O2 sensor, (but it isn't recomended and not a good idea). Third port is for the O2 sensor for OBD1 s13's, technically the first O2 sensor for OBD2 s14's should go there. Second O2 was designed to read the difference in CO2, O2, and HC conversion (AFTER THE CAT). Putting the 2 sensors next to each other down the header is POINTLESS!

You guys haven't been searching I did the thread on how to install them.

having the 2 sensors next to each other is pointless if your running a cat, but if u have no cat it doesnt really matter because the hc, etc is the same
