To put it another way, how about the nay sayers providing date which
CONTRADICTS that adding an improved exhaust system will add positive
results, throughout the entire rpm range.

A sucker bet if ever one was proposed. Even the sharpest critics of
aftermarket smoke pipes have not (AFAIK) claimed they're all
completely useless. Why don't YOU supply some credible data showing
measurable LOW RPM improvement on any rv sold in the last 15 years?
[Ad hype and SOP testimonials do not qualify as credible]

Real-world experience trumps unsupported opinions. Mr. Sill offers only
unsupported opinions, and dismisses real-world experiences that disagree
with his opinions as not "credible."

The power required to push a gas (air, etc) through a pipe rises
dramatically as the volume increases. . . but at very low volumes
even Oz could blow through an elderly class C's smoke plumbing with no
loss of performance.

Mr. Sill--once again--demonstrates his complete ignorance of gas-flow
dynamics. There is *far* more to efficient exhaust-system design than
simply lowering restrictions


I don't know anything about gas flow dynamics, but my hunch is that Mr. Sill
is correct.
In this world of one-upmanship by the car/truck manufacturers who all want
to claim "best in class" bragging rights, why would they hinder the
performance of a work type engine (i.e. Ford V10) by going cheap on the
exhaust pipe diameter or using inefficient headers? If it were that simple
to gain some extra low end torque, don't you think they would do it from the
get-go? I suspect the only way to increase low end torque (at the expense
of high RPM performance) would be to change the cam. In the old days, before
modern, high revving engines, the type of cam is what differentiated a
"truck" engine from a regular car engine of the same displacement and
design.
