I don't personally, but I can rent a scuba tank and fill it to 5500PSI for about $35 USD. The tank is about 1500 CI

If you didn't read my earlier post, here is a repeat: The store near me only sells the extreme pressure cast iron pipe capable of sustaining 6000 PSI.

What, screwing it in, or welding it on? I am not thrilled about the idea of a screw shooting out with 5500 PSI behind it

Ok, I built a noisemaker just like the one you want to. It was a piece of scrap SCH40 1.5" ID pipe, glued a cap on one end, put a small hole (1/2") about 2" above the cap.
