This manifold was designed to improve on all aspects over an OEM manifold. The manifold is cast from a high molybdenum-steel metal with the exhaust flange and center divider thickened for greater strength and durability. The joints were designed as a press fit, with tight tolerances creating a 50% increase in surface contact.
