If you do enough stainless piping to justify it, these plugs come in pretty handy.

I believe there is some sort of flux I can apply to prevent sugaring if purging will not, does that work satisfactory?
Don't know about Cav, but memory says there is a flux that can be put on the backside and used with back purging. Ideas?

Solar Flux. I have a can of it somewhere. Mix it into a paste with methanol, brush it on, let the methanol evaporate and weld. It does create a hard glazed surface on the backside that is sometimes a bit tough to remove. Wouldn't be an issue inside an exhaust.

Yeah, solar flux is good for non-food grade or where the flux won't cause damage over time as it breaks apart and travels through the piping. Good fitups with no gaps are important if the flux is going to work properly.
