Zeroed has got it exactly right about the size, scavenging effect and what 'back-pressure' is.

The correct relation is PV=nRT, with n being number of mol (1 mol = 6.02x10^22 particles).

Anyway, you don't want to cool it down because that will only increase the density, and denser gas has higher inertia like a heavier pulley is harder to spin. You want to keep it hot.
Then there's a consideration on the piping size too as bigger pipe has larger external surface for heat dissipation. Like what Zeroed has pointed out on how the size affects velocity and scavenging, it affects the temperature (and then the density, then the pumping lost) too.

V is volume. This is the Gas Law for for gas thermodynamics, not fluid dynamic.PV=RT
P = fluid pressure
V = fluid velocity
R = fluid constant (I guess)
T = fluid temperature
The correct relation is PV=nRT, with n being number of mol (1 mol = 6.02x10^22 particles).

You started with using the wrong formula so.....Therefore I was wondering is it possible to cool down the exhaust temperature? Because due to the formula, high velocity, low temperature exhaust system can create less pressure thus can pull out more exhaust gasses from engine cylinder. Is my assumption correct?
