Bash: capture the echo of a script in a variable

I have script1 which calls script2 which contains an echo statement. I want script1 to send the echo returned by the script2 to a named_pipe. Is there a way to do it without having to change the code of script2? Like "capturing" the echo statements?

SCRIPT1:

...
case ${input_args[0]} in
        SCRIPT2)
            ./SCRIPT2.sh ${input_args[1]};;
...

SCRIPT2:

echo "OK: done!"

Just redirect the output to the named pipe:

./SCRIPT2.sh ${input_args[1]} >"my_named_pipe"

Named pipes are just like files in this sense.
