Dylan Devlin hit back with one for the Thunder to end the first period, but Braden Lee and Mike McRae soon made it 4-1 to the Stampede.
Jack Robbie added a fifth in the final period, and while Noah Gregory pulled one back for the Thunder, Harrison Macharg had the final goal.
A first-period blitz did the damage on Saturday.
Lee and Devlin exchanged goals early in the game.
Then Macharg, Harrison, Schneider and Patrick Volpe all found the net to make it 5-1 to the Stampede at the end of the first period.
Maxwell Macharg and Sean Anderson added two more for the Stampede, before Joe Orr hit back for the Thunder.
That made it 7-2, before Schneider scored twice more to complete a resounding victory for the Stampede.
