I know that the d16y7 has 2 o2's in the stock exhaust header and I imagine the greddy kit for the 92-95 ex(that I should be receiving anyday now) only has one hole in the DP. Any ideas on this would be greatly appreciated? If one o2 has to go, what do I need to make everything still run smoothly. Thanks,

i think the second o2 sensor should be after the header and is actually after the catalytic converter and should be left alone. it will still be there after you install the kit.

ttt for what exactly?

 

Your gonna have to extend your second 02 and get a cat with a 02 bung at the end of it.

I was just looking to get more opinions, maybe from someone that has my setup, sorry to offend you

 

y7 has cat at top of header, o2 at top of manifold and below cat. you will need to get new cat. primary o2 goes at end of dp and secondary goes at outlet of cat. you need both. you will probably get bad bogging until the primary heats up. had that problem when i went from stock to dc sports 4-1 header before i went turbo. just make sure your car idles until it heats up everytime you start it or you will not get any good fueling and bogging issues until it does. when i went turbo i went custom and am using a std/hf manifold that has primary o2 in the exhaust header before turbo. no more problem with bogging at cold or warm start. i just use the sensor hole at end of dp for wideband o2 sensor tuning.
