but.. if the o2 sensors are placed away from the exhaust stream they will generate less voltage, same effect as using a resistor in the line...

i would say it will work, not becuase of the slowed down gasses or something but just becuase they will show the ecm a lower voltage reading, therefore the difference it was looking for.

not sure though if the ecm wants a lower or a higher voltage reading from the after cat sensors, it may be necesary to install the spacers in the front O2 sensors... maybe?
