[theory] Exhaust size/restriction vs. power

["Neal Tovsen" <sixteen.volt@verizon.net>]

OK, Scott. Normally I have completely blind faith in your words of wisdom,
but you just said one thing and then (on face value) *completely* negated
your first statement.

I'm NOT going to argue that you're wrong in your overall point, because you
probably know more about it than I do. But let's just analyze what you said
here, so that we may actually determine the facts that support your
statements.

> NO ENGINE BENEFITS

You (and Dan, FWIW) never actually say a word to support this statement.
Please support it. If anyone has dyno charts, I'd love to see them.

On face value, you just completely went back on yourself. On second thought,
maybe I caught something here that took a little "2+2" work in my brain. Did
you actually mean to say that a "smaller diameter" exhaust is **different**
than a "more restrictive" exhaust of larger diameter? If I'm on the right
track, take me further (explain how it is different)! If not, what did you
actually mean to say?
