This is system-dependent.  BSD kernels (recent ones, at least) do
indeed handle #! on their own; I understand that SV kernels generally
do not.  (I don't know about any others, eg V7/V8/V9, SIII, etc.)

As you probably discovered, you don't: you use cat instead of echo.
Using echo here makes about as much sense as saying

cat textfile | echo
