      My guess is that it has some give when it expands & contracts.

      It has a lot of uses.

      First being that stainless tubing has a very high thermal expansion rate. So when it's 1200F in there it moves around quite a bit. If you don't have some flex sections it will crack and break.

      Also on some setups the turbos are not hard mounted to the engine, but to a frame section. In this case (unless you use solid motor mounts) there needs to be some room for movement and flex in the system.
