Its entirely a result of the Placebo effect. If you wore some sort of full sound suppression head gear, and drive a car with/without the Y8 manifold... you wouldn't be able to tell them apart. Even if it netted you 5whp, the likeliness of you being able to notice that small amount of power is virtually impossible.
