This is a Formula 1 exhaust manifold.
You can see how each port from the engine has a unique length runner, mathematically calculated, so that the pulses can pull the next pulse out with ease. Chucking a fan in here, would need to spin much much much faster than the engines 18,000rpm limit to extract the gases out without introducing any restrictions
