Fresh off a 4-0 win over Bangor last week, Institute travelled to play H&W Welders in the championship.
The Sky Blues took an early lead through former Finn Harps player Michael Harris in the fourth minute of play.
Institute midfielder Ryan Morrow was sent off just before halftime as the visitors went in 1-0 up at halftime, with a man down the home side made them pay as they went on to score four goals in the second half to win 4-1.
Stute sits in third after today’s result and will play Portadown next week.
