Looks like a silencer for a aftermarket muffler. Good luck.
Greetings Mr. Cobbler: I am building my own exhaust mufflers for a 1973 Yamaha RD350 motorcycle that I am restoring. This is basically the part that I will need to weld on the end of the muffler pipe. On this will then mount the silencer end can. I have bought aluminium tubes of 3" OD... Worst case, I will have to just buy a mild steel pipe, cut it and then weld plate, drill a hole in the center and weld the small tube as is in the picture. I was hoping that I could find something similar or even a metal cylindrical/round cup where I could just drill a hole and then weld that stinger pipe in it.
The one I have in the picture is the part sold in Japan by a Japanese vendor and its out of stock.....

Look up aaen performance, under exhaust in the snowmobile section they have a silencer with that style cap, I would call them and see if they will sell separately ( or just buy the complete silencer).

That type of silencer was commonly available years ago for those who ran race pipes on the street and at tracks that had noise regulations. I think there are still sources for them. You might try to search for Yamaha aftermarket dealers in the UK where many people still run the 2-strokes on the street. In the US, the vintage racing group AHRMA might be able to help you.
Here's a forum that covers Yamaha 2-stroke racebikes. Someone will be able to help there.

You could draw a piece of sheet over a form fairly easily to make that if you want to turn your hand to some sheet metal work. Plenty of resources on YouTube to show you how if you aren’t familiar
