It's all guessing from the outside until you disassemble and inspect components.

With the pipe removed, looking up thru the exhaust port do you see if the piston and cylinder look damaged?

 

Ideally you shouldn't buy any parts until you've determined what wrong.

Even if it ends up being the piston/cylinder, there's no guarantee those parts are of the required size.
