Mystery exhaust

I had posted this in the engine section ( Tecumseh ) and was going to maybe fit it to my Manco Chopper . Someone mentioned it may be to a Scat Kitty ? I don't know what it's to as it was in a load of parts I bought,,but it does appear to mount to a Tec side popper and really is in like new shape.
Anybody recognize it ? Any experts ? Help?
I really don't want to alter it if it's something worth leaving alone :scared:
