What to do About O2 sensor?

[stegosaurus]

Searched a good while, and haven't found anything. Please point me in the right direction if I've missed something.

My muffler had a lot more rust on it than I thought and a stone separated it from the rest of the exhaust. I got a replacement catback section and the cat section fell off in my hand when I was fitting the catback today. The cat is held in place by drywall screws (PO was a champion) and now my car is even more illegal than it was.

I'm not about to spend money on a cat considering I'll be swapping the motor in the near future (S38 FTMFW) and since I have access to a machine shop it shouldn't be a big deal to make a connector.

In order to pass inspection I can't have a CEL, and so I'm wondering what people are doing with their 02 sensors in their straight pipe cars. Can I fit a resistor to the sensor? Can I simply fasten the sensor to a frame piece so it can still transmit a signal? Should I try and fit the 02 sensor in the new piece?

Thanks for any help.

I have a 90ix with no cat. I don't get a CEL. Perhaps your CEL problem is else where?

I have a 91 m42 with no cat. I don't get a CEL either.

Lawlz have a exhaust shop weld in a new O2 bung.

A straight pipe wont throw a code on a car with no rear o2 you don't have a obdII

Oh alright then. A friend of mine was telling me that I would have to deal with codes because of a lack of input into the O2. So I can just get rid of it? Will this have any affects on the the air fuel mix?

No, don't get rid of it. It will have some effect on fuel economy.

So it needs to stay on the car, can I zip tie it to a hangar or something?

I don't understand what you asking.

[stegosaurus]

I don't understand what you asking.

I took what you said to mean don't tear the 02 sensor off of the car. In that case I figured I'd have to attach it somewhere since it wouldn't be mounted in the midpipe.

Were you saying that I had to keep the 02 sensor in the plugged into the pipe? I guess it wouldn't be too terribly hard to weld the bung into the new pipe.

OP your a Fucking Idoit Go to an exaust shop and have them install A new O2 bung in your new mid pipe so you can run your O2 sensor.

Fucking idoit? Never heard that one before. I've got nothing against taking it to a shop but I know some people run without them and I wanted to know how it worked.

Thanks for being a prick, you spelled exhaust wrong too.

[416stroker]

OK I spelled it wrong. If you dont whant a cell install you 02 its simple. I doubt you can do it your self since you asked this retarded question. So take it to an exhaust shop.

damn someones a lil pissy...but kinda have to agree the "zip tie the o2 somewere to the car" thing was a bit retarded

[drift]

Stegosaurus, you should consider this :

i just cut mine out from between the stock m20 pipes and cut the y pipe on the M50 with my plasma to size and welded it in...but i doubt OP has a plasma nor welder...nor common sense
