Anyone use these to turn off a CEL using a test pipe?

Though these could work for you, I've seen documentation that longer ones are needed. You might run into the issue that these shorter ones will still keep the sensor reacting quickly to AFRs instead of slowly with longer ones.

>>>UPDATE<<<
Installed 6 new coils and plugs, 90° fittings with spacers drilled, two new NTK O2 sensors. No more miss or CEL after 9 months of living with it blaring on the dash and rich condition! Still rich though 12.2:1ish/no cats. Coil was diagnosed when swapping to #3. Pulled out 110k plugs on 1/3/5 bank and they looked normal. 225k miles and still pulls like a champ!!!. The coil is the only thing that has failed on the car in quarter mill miles! Nissan (Japan) reliability rocks!! Just hope my F80 is close to this standard...
