theres one on the header and wheres the other one?

 

if you have a 1996 or newer prelude its in the catalytic converter.

 

so i would either run my wires for a A/F ration gauge to the cat or the header?

 

also, what kind of o2 sensor comes stock with 5th gen? wideband or narrowband?

narrow

 

Awsome, this will be good to know once I get my setup

 

You don't wanna take out an o2 to stick the wideband in there you should weld the bung (they should have sent one with the wideband if you did aem) onto another location on the header, your ecu will throw a cel inless your running an aftermarket ecu setup.

 

with a wide band you wont get the open close bounce would you?
