I am planning on buying the LC Engineering Header for my 22RE. It has the O2 sensor down by the catalytic converter, correct? My 85's O2 sensor is up on the manifold. Would I be able to extend the O2 sensor wires down to the mount without messing up anything (electrical resistance???) or will I have to mess up the ceramic coating to mount the 02 sensor fitting they provide if needed up by the engine.
