I won't say that it is the case with the case with this exhaust system, but have you heard of Bernoulli's Law? To sum it up, "For a non-viscous, incompressible fluid in steady flow, the sum of pressure, potential and kinetic energies per unit volume is constant at any point." The short version means, as the velocity of the flow increases, the pressure drops. That is how an airplane wing develops lift.

The same thing happens in the flow of a gas through a tube. Where the tube becomes narrower, the pressure drops. If the rest of the exhaust sytem (past the leak) has little back pressure, you could --
