Why upgrade my exhaust manifold?
As one of the easiest bolt-on additions, headers are a great way to increase horsepower and torque to your vehicle.  In a normal engine, exhaust gases exit your engine's cylinders and ends up in the exhaust manifold.  From there, the gases move into the pipe that leads to the catalytic converter and muffler.  Unfortunately, the manifold can be a primary of back pressure.  Headers are made to eliminate your vehicle's manifold's back pressure, increasing horsepower and torque.
