Oxygen, Air/Fuel Sensors

Does anyone make a reasonably priced A/F ratio sensor that can be put in the exhaust (tail) pipe for testing and then removed when done?
Thanks,
Archer

That would fall under a specialty tool so it’s not going to be cheap.

Thanks, Kinda what I was afraid of.
Why wouldn't a regular "weld in" sensor that goes into the header collector work at the tail pipe?
I think I know the answer, just tell me I'm wrong.

It probably would but if your going to buy one why not just not mount it permanently in the exhaust?
If I had more than one project car that I wanted to tune with it I would put a bung in both cars and move the works between the two cars.
I don’t know what other people do but I tend to spend my time tuning my carb and timing initially and then I tend to not need to work on them again sometimes for years…
while others are having to work on there carbs every time they drive there junk, I can’t tell if they are picky or don’t have a clue.

I like dealing with facts, I can "think" my A/F ratio is correct, but I'd like a way to test it throughout the rpm range. .
As strange as it sounds, I just don't want to deal with more wiring, and since I don't weld. I'd have to have it done.
And technically you'd need one in each collector.
Basically, I'd (re)check the A/F ratio when I changed part of the induction system.
The do make tail pipe adapters that hold the bung, but you'd have to match the adapter to the size of the tail pipe.
Just wondering if there was an easier workaround.

Less soot up from... More heat for the element and the chemistry is better than out back.... Just a simple version...
Out back it too cold, sooty, and damp. Hurts the heating element and also plugs the sensor and causes per matured contaminant failures..

The best place for them is just after the collector, I see a lot of guys putting them in the collectors but the air needs to blend before it’s ready for the O2.
