An enthralling first half resulted in five goals with a double from Paul Hayes following a strike from Dan Butler putting Michael Flynn’s hosts into the ascendancy.
But an early own goal from Butler and a first-half strike from captain Gavin Gunning kept the visitors in the game.
The Exiles endured a nightmare start when Butler put the ball into the back of his own net after a wicked cross from Haydn Hollis after six minutes.
Butler quickly made amends when he equalised after finding the right end with his right foot just three minutes later.
The home side went ahead for the first time 17 minutes in when Hayes’ header found the back of the net after an initial header from Butler.
The Green Devils hit back when Gunning was found unmarked and fired the ball home, while Hayes put the Exiles back into the lead with a powerful volley on the stroke of half-time.
But Collins ensured his side went home with a share of the spoils with eight minutes remaining.
