You don't even need that. Spark plug non-foulers work fine.would this device work for our cars assuming we have gutted cats?
Jeremy: I have trouble visualizing how this works... do you double the bungs and still let exhaust gas get to the sensor? Or are the bungs just dummies with no open port to the exhaust (in which case I wonder what signals it would generate)?You don't even need that. Spark plug non-foulers work fine.
Interesting!Yep, that's exactly right. You screw the non-foulers into each other and then into the exhaust pipe, and screw the O2 sensor into the top non-fouler. The top-most non-fouler usually has to be drilled out slightly because the tip of the O2 sensor is too big for the little hole in the non-fouler. A little exhaust gas still gets to the sensor, but apparently not enough to make the sensor think the exhaust is dirty, even without a catalytic converter. I ran my car that way for a couple of years and never had the check engine light come on.
this is the route i will go then, if non-foulers are proven thanks guys and removing o2 sensor via a tune still won't pass NY emissions which is an obdII test
for the post cat O2 sensor, you can use the spark plug non-fouler trick.

Re: Do it yourself o2 simulator
It works, and there is no need to cut any wires or anything...very easy as well.
I personally have driven about 300 miles since, no CEL. So anybody who wants to run a test pipe...here is the mod you should do to stop the CEL...don't bother with the electronic ones with only some of them working...and not working all the time. These pics are from it being done STi, but I did it on my S, works just the same.
Those are the Spark plug, Anti-Foulers you'll need to do this..just pick them up at any auto parts store
