Thread: Removing the Rear O2 Sensor and Getting Rid of the CEL

That's exactly what it does...

Very nice find Swiss!

So in this case I would still need to probably extend my O2 sensor to the downpipe and plug it up there with the fouler...

What do you guys think of these test pipes?

Please post links if you have anything better in mind

This one is a little cheaper:

S13 is the same size as 91-97. Some of them have heat shield brackets you have to cut off, but they fit great.

Thats a pretty good price

So do you guys think its worth going for a Test pipe? Will it make the exhaust louder?

I personally would much rather have a real cat on a NA car.

I agree, I don't want to take the hummer way out yet...

If no one has one, I might just cut my exhaust and use clamps to put it back together...

As Swiss posted, here is the O2 sensor engine light "hack"

Does anyone know how I can make the CEL for Rear O2 sensor disappear? Other then having to spent a boat load of money on a new one

Resistor mod.

That's the only way to really make it disappear.
