Adverse affects of removing sensor after catalytic converter

[micus]

hey, i was wanting to get my cat removed in my 95 talon, since i already have a cat back, and my dp is comming any day now, the only problem is none of the garages around here want to take it out for me because there is a sensor behind it? but there are lots of 2g's running catless systems, so i was wondering what bad will happen if i do take the sensor out and what to i have to do to make it safe????

You can just wrap it in tin foil and tuck it up under the car.

At worst you will get a Check Engine Light, but that will affect nothing.

some DSM cars don't throw CELs, my brothers car was one that likes to throw a CEL for any possible reason it can. What I did was took a spark plug anti-fowler in the correct thread/pitch (I'm thinking it was 18mmx1.5 - may be wrong). The anti-fowler was hard to find for that pitch, I just happened to be at this small parts store on a different side of town and scoped it. I then filled the bottom hole with weld (make sure that 2nd sensor doesn't read any exhaust gasses). I opted to drill 3 holes in the piece so the sensor got some nice fresh air to breath.

The end result fits cleanly under the car and I don't have to worry about the sensor wiggling around on me, it's plugged into it's intended spot with a small spacer.

Of course I could have wired up a simulator but I opted for the cheaper fix.

The only thing the rear o2 sensor does is make sure the catalytic converter is working, it's for emissions. The following link is how to do the simulator/bypass:

There's also many threads about the rear o2 sensor here: http://www.dsmtuners.com/forums/search.php?searchid=2166467

I don't know if you live in an Emissions state, but you will be fined and fail the test if you get an emissions test done and you don't have a catalytic converter. I think the fine is $2,000 it is a Federal Offense to tamper with or remove the catalytic converter. I know lots of people do it and I would do it if I could afford the fine if I were to get fined, but I just wanted you to know what you were getting yourself into. They are illegal unless used strictly for race track or off road purposes.
