Support the car and unscrew the two bolts from the outlet flange of the manifold. The Oxygen Sensor should be eliminated if needed.

A thorough inspection together with cleaning must happen for the Exhaust Manifold. Place the outlet pipe inside the exhaust crossover pipe partially while positioning the manifold for installation. Fasten two bolts around a new gasket placed on the manifold surface. Professional manufacturer offers an outlet pipe allen wrench for assembly along with a torque wrench to apply 25 nm (18 ft.
