Absolutely. Ball & slip joints are “standard”, and necessary on many aircraft exhaust systems. A ball joint between a tail pipe & the rest of the system is very common on Lyc’s & Continental’s. Also, for several reasons, the generally accepted “correct” stainless steel alloy is 327. I have to assume & hope that’s what Kitfox uses.
