there should be no need to touch the o2 sensor. that manifold is actually called the downpipe. maybe you got an LX header because those have the sensor in the header.

~Dats what I thought.... dude was tellin me that when you go to add a aftermarket header that you remove the manifold at the same time and take the manifold O2 sensor and attach it to the header ~
~ Plus there is a O2 sensor attached to the Cat also.. right? ~

the guy is right but that's if you have a manifold like the lx. the ex doesn't it has a header. so basically you should have gotten an ex header not an lx header. the cat attached to the downpipe underneath the car has an o2 sensor.
if you have the header that goes under your car this is what i did:
there are two sensors on the downpipe/ cat, the one in the engine bay gets pluged into the threaded hole on the bottom of the header just before it bends under the engine, the second one will be pluged into the aftermarket cat you bought
lol sorry i didnt realize you were talking about a totaly dif header

Reason: didnt read it right
anybody know how big the diameter of the actual piping is? from the innerside that is, not outside.
im in the market for a header but i dont know wheather i should go with dc 4-1 cermic or the hp cermic. i know the hp got biggers pipes, but with smaller pipes > higher pressure > low end. so if anyone can measure either the hp top portion header, and/or the dc cermic header... i'd appriceate it. 100 pts if u like =D
i just bought a HP full header, and its sitting down in my room ready for the install (great DIY by the way) and its got 1.5" piping on the inside edges, only thing is its for a 6th gen EX, 7th gen might be different
over spring break, i'll be putting it in along with my whole exhaust, ordered a tanabe SRM, custom 2.25" piping, big resonator for pressure and to quiet it down a little lol, and high flow cat, i freakin cant wait... next week!
btw, anyone know if my setup is street legal? i've never had to have a sniffer test done in AR, but i dont wanna have a nasty suprise if something comes up...
