Hello 991ers We are now offering our equal length race headers in a ceramic coated finish. With our special 3 to 1 merge collector and equal length tube design, the power band became extremely linear and consistent with no hesitation or issues. In some areas of the curve it gained 30ft/lbs of torque! The Agency Power 991 Carrera Headers gained a peak of 11HP and 12ft/lbs of torque.
