To paraphase Berneulli.
If a gas flow is constant the only way to increase velocity is to introduce a noozle or some other resistance to flow. To do so increases what we refer to as back pressure.
This has been proven in physics and accepted unil it is referred to as Berneulli's Law.

You know the old V1/P1 vs P2/V2 that were taught in high school physics class.

Sorry can't remember name spelling or exact formula, high school physics was 50 years ago

One of Bernoulli's laws is:

1/2*rho*v_inf^2 + P = const.

where rho is the fluid density, v_inf is the relative fluid velocity, and P is the fluid pressure.
This means that for compressible fluid flow, the sum of the dynamic pressure and the static pressure are a single constant, and therefore, dependent on one another. To obtain the highest fluid flow you would desire the lowest pressure. Introduce a converging nozzle; the fluid pressure, P, is lowest at the smallest diameter and therefore the fluid's velocity increases. Note that this applies only to subsonic fluid velocities; for supersonic velocities, it is the exact opposite.

That's why scramjets work! Theoretically.

Can someone explain to me why I need to spend $111 for this over my $40 glasspack?

Also not thrilled about moving parts in muffler. Moving parts in a sealed non serviceable environment equals waiting to break.

So that the company succeeds in duping you to buy their product! Yay!
