Depends if the flow path is smoother, straighter, and has the same cross
section all the way through. A 4 foot long straight tube with consistent
cross sectional area will flow more air with less turbulence than a 3 foot
long tube that changes sizes and has bends in it. there are actually
formulae to calculate the flow losses caused by bends or tees, or any other
trait that causes air (or fluid flow) to change direction or speed. A good
example is an intake port on a cylinder head. It is common to raise the
ports for racing in order to have a straighter shot at the valve, and even
though the port is longer, it has the same cross section and flows
substantially more air.

I think you are putting you and your family in DANGER by installing that thing.
Geez.
