A simple kit is the AEM 30-4110. Here's the cheapest place I found selling it. AEM 30-4110 Wideband UEGO kit - Great for Monitroing Air-Fuel Ratios - new LSU4.9 sensor Before ya go drilling holes you should get the kit and read the instructions. My kit said sensor needs to be at least 18" from the exhaust port. I installed mine in my double wall tails like Eddie Young showed doing it in the link. It's incredibly simple doing it that way. Here's some wideband compare info.....https://10carbest.com/best-wideband-gauges
Put bungs in both exhaust. You can run the double kit or 2 of the single kits are cheaper. Or just a single and switch back and forth and compare.

They are a great addition if you run to guages at dash.. but make sure that they can be seen as the gauges don't seem to have the same characteristics as Livorsi/Gaffrig gauges. Sun hits mine at any angle and cant see.. mind you mine are digital display. maybe my mistake

I use this. I've done before and after testing with this on the same motor, same day, same tune. No difference in AFR readings or response time. Provides a little extra protection should any reverted water drip downward from the elbow towards the wide-band sensor. It is meant as an extreme heat shield for turbo motors but also works in defending against reversion.
For those drilling in and welding in bungs at the bottom of a standard Merc style elbow you can get a Wags engineering spacer or one for LA Boat Parts that is much simpler.

Ive had good luck with these (link below) for preventing water on the sensor. It does delay the response time.....so I wouldnt use it for accelerator pump tuning or other quick transients....but for steady state stuff it works well.

maybe I have less water or less reversion ..... who knows......the bung is on top of the collector as close to the primaries as I could get it.....I never tried a sensor without the 90* fitting I linked.
Did the one you tried have the reduced inner diameter/orrifice before the gas enters the "chamber"?
