Wigan survived a second-half comeback to scrape past Catalans - who played the whole of the second half with 12 men after Kenny Edwards' red card.
The visitors led with Jodie Broughton's try but at 8-6 down had Edwards sent off for a late tackle on John Bateman.
Morgan Escare scored for Warriors against his old club as they moved 20-6 up after half-time and well in control.
Two Catalans scores and a penalty made it level but Sam Tomkins' drop-goal and Joe Greenwood's try won it for Wigan.
Victory moved second-placed Wigan three points clear of Warrington, with Catalans slipping to eighth for the start of the Super 8s.
Chris Hankinson and Greenwood grabbed their first tries for Warriors, while Tomkins scored 13 points against the team he will join in 2019.
The French side looked like overcoming a 14-point deficit despite their man disadvantage as Arix Da Costa and Fouad Yaha crossed, but the home side regained their nerve to see out the win.
