Execute awk output

Question

while read line;
do
  awk '/ differ$/ {print "diff "$2" "$4" > "$2".diff"}{}';
done < diffs.txt

This prints the command exactly as I want it. How do I tell it to execute the command?

| bash does the trick...

while read line;
do
  awk '/ differ$/ {print "diff "$2" "$4" > "$2".diff"}{}' | bash;
done < diffs.txt
