Hey, it just occurred to me, for testing headers for flow, 
which
sounds like a bunch of effort since there's 4 outlets (per 
V8
side), why not flow them backwards?

Attach the outlet (bottom) to an air source, put a false 
extention
on the "inlet" end for a few inches, measure 
pressure/flow there?
Pipe is stupid, it doesn't know left from right.

Somone on the JYTurbo list tested Intercoolers
with a fairley simple air source & meter >
last year..... I'll see if the info is still there.

Best Mufflers I know of are the SuperTrapp 
Disc Type > patented< that mount to the
end of your exhaust Pipe....... comes in Stainless
Steel & you can Add or Remove serrated Discs
for Louder or Softer and these only allow the
Exhaust to Exit .  Once the Flow Pressure drops
these Discs clamp shut > blocking 'Inhale'.
No other Muffler has this feature > that I know of.

Originally Designed for Race Motorcycles back 
in the late 1970s.
