We have had several cars come through with stepped headers but could not quantify any notable difference since it was not in any back to back testing.
Same goes for the Tri Y Headers.
There is a lot of Header technology that makes power BUT
When you going through a full exhaust system the fancy headers can not show there true ability.
I know we would see advantages in an open header situation that is a fact.
