I am not sure but 15rwp over the shorties is still a gain that I will take. I have read that the JBA'S I had on the car flow the best of the shorties.I read a thread were they gained 8rwhp over the Z06 manifolds. My point is I gained 15rwhp over headers that make more power than the manifolds to begin with.
