The dyno graphs on page 3 do seem to indicate a genuine gain if quite small, a smoother power curve and also no loss of power anywhere across the graph. Just seems an easy way to gain a few HP and a better exhaust note for free. Does the switchable sports exhaust on N/A Porsches not effectivly work in the same way by the flap opening to let some of the exhaust gases escape the main silencer body?
