The second-half started with a much better pace and intensity, which Congo progressing with more optimism; they went ahead when Bifouma swept home a cross from Dore in the 51st minute.
They nearly doubled their lead with 18 minutes to go, but N'Dinga's powerful shot was saved by the Stallions goalkeeper Sanou.
