exhaust question

hey i changed the exhaust on my car to an aftermarket one then i switched it back to stock and my stock one now for some reason sounds a lil louder/deeper than it was before. I was thinking by changing the exhaust do i autmatically change something else (i.e. golf tee mod or that vacuum mod people talk about? or any other ideas why this might be so?
