2024 GT mustang whistle

My GT is making a whistle sound when it accelerates, doesn’t do it often, here and there. Only when I go hard on the gas really is when I hear it. It has active exhaust and it sounds like a weaker sound like when a truck spools up and accelerates, best way I could describe it, or the sound of a turbo spooling up. Only just started doing that sound the last couple days.
