the exhaust manifold is also known as the header. it takes exhaust gasses and routes them down though the catylitic converter then to the muffler and finally the atmosphere. the exhaust manifold itself stops just before the cat. on just about any honda any normal person can get their hands on, excluding some of the new motors, this is located at the front of the motor. it is covered by a heat shield, which some motors have a hole in for the dipstick. hope that helps.
