would like recommendations for a good quality exhaust back pressure tester. Thanks

A vacuum guage will tell you if the exhaust is restricted.

I had one from mac or snap on. But as busy as I was I found it easier to just take it to the local muffler shop and have them check it.

How does that work?

Positive lead diagnostics on YouTube used the HF vacuum tester with a bored out old o2 sensor. It lead me to go by the $15 tester. Seems like a cheap option for something I don't use much.

Guessing the engine lacks power ?

Converter is the likely cause of the exhaust flow ......drop the converter and visual inspect.

Honeycomb substrate melted or damaged......easy to see with the converter inspected and more conclusive than the gauge tests. Gauge test will give good results if the flow is low.
