  A: The first step to replace the right Exhaust Manifold (W/O NC8) involves removal of both the fuel injector sight shield and disconnection of the heated Oxygen Sensor at the sensor pigtail. First remove right side spark plugs before unfastening the two nuts that attach the power brake booster heat shield to the exhaust crossover and afterwards take off the heat shield. Detach the two bolts which secure the exhaust crossover to the right Exhaust Manifold along with the transaxle filler tube. After raising and supporting the vehicle remove the Exhaust Manifold pipe and heated Oxygen Sensor depending on whether replacing these components is needed. Start by removing the nuts which retain the fuel injector sight shield bracket and its bracket component followed by taking apart the retaining fasteners of the right engine lift bracket and its respective bracket section.
