I used to have a exhaust reader that slid down into the exhaust end to read Lamda and air/fuel ratio. It was ancient and huge but worked great. I sold it and kinda regret it now. I know Koso sells one but I don't recall if it bung attached, like you are trying to avoid, or if it slides down into the exhaust end.
The reason they mostly use the bung attachment is because modern exhaust use catalytic exhaust and any reading after the cat will give a false reading if read after the cat, hence the bung before. The exhaust we used our old school one on were expansion chambers on 2-strokes. No cats in those.
If I tune now I just do plug chops. It's time consuming and annoying but it works. I'm in the process of putting a bigger main jet in my Buddy 125 when I get off my butt.
