HKS Turbo Exhaust Manifold for the Subaru WRX and STi is an OEM replacement (using the standard 2 bolt uppipe connection) which comes with gaskets and a heat shield blanket. The HKS headers are lighter and flow more efficiently than the factory manifold which will increase your horsepower and torque while giving you a more aggressive sound.
