Headers in combination with the right exhaust system will give a good increase in performance for any supercharged engine. Especially those with a mechanical driven supercharger. Turbocharged cars are different in that the turbine acts as a pressure barrier.

However turbochargers do benefit from a good manifold design with individual runners with the right length. Manifold volume plays a part too. After the turbine you do not want to build backpressure of any kind as this hurts turbo spool up time and restricts power output.

Example from my own experience: Dodge Ram SRT/10 with paxton supercharger produced 580rwHP and 750Nm of rwTQ. After fitment of B&B headers and 3" exhaust output rose to 640rwHP and 880rwTQ. With the high boost pulley this puppy probably produces over 1000Nm of rwTQ! (Imagine a 2300kg pick up truck out accelerating more expensive and 'faster' machines... 450Nm from idle rpm... need I say more...)

With a good header with the 'right' exhaust system, engine volumetric efficiency will be higher. The engine will pump more air. So if you add enough fuel for the correct mixture power and torque figures will rise accordingly.
