With all said, I agree that the shorty intakes lose power due to heat soak, But maybe they used the first or second run only? Also I think I would be more apt to ask why the car only made 286 with headers and and HFC's. My car made 298 with stock cats and headers? ( mustang dyno) Not inflated numbers/
