The expansion chamber doesn't surprise me a bit. At the drag strip there was a ported to the nuts 12A car and it had the typical 2-stroke ping-ping exhaust sound.
One of my old co-workers was a rotary eccentric (see what I did there?). He would spout off all about how awesome they were all the time. Yet in the 3 years I worked with him he went through 5 FB's 12A and 13Bs and blew up an FD. I've handled more rotary guts helping him rebuild them than is probably healthy.
Him: "There's nothing wrong with them once you dowel pin the barrels, replace the apex seals, ditch the emissions equipment, add oil to your gas, and rebuild them every 60,000km because there is no indication from the apex seals about when they will die and seize your motor..."
Me: "Uh, right. What killed this one?"
Him: "I won't know until I take it apart."
I still envy their packaging, though...
