the only actual test of performance we ever did was we removed a set of dynomax magnaflows (which do flow really well) from a 71 Camaro with 327 and put on a set of shuttle worth stormer performers (turbo style) and his 1/4 mile times improved. you can call shuttleworth and they might have flow bench data on the bottle mufflers too. they are more of a truck muffler company so I don't believe really inclined to BS flow rates on the numbers of there smaller stuff. Its not there bread and butter.
And Canadians never lie right? ;/)
