277 exhaust intermediate pipe?

The original 277 on this plane was stolen.  A replacement is on, but the original muffler can't be mounted to the engine.  Based on videos of the plane before, and looking at what I have now, it seems that there was some kind of intermediate pipe that went between the short pipe that bolts to the engine and the muffler, a gap maybe a foot or so in length.

Is there maybe a FLEXIBLE intermediate pipe that has the male ball on one end and the female ball on the other?
