I looked at scarbs very interesting post mentioning an exhaust 'chamber' where pressure is 'acumulated' and released when off throttle, thus providing flow when off throttle. http://scarbsf1.wordpress.com/category/ferrari-f150/
In fact more interesting pieces on the page pointing to teams wanting to blow exhaust gases under the rear wing to energise the flow and create downforce...
As for the affect on engine performance/resistance, no idea if there is a valve or something to alleviate this, also its stored in a seperate chamber and not the exhaust trumpets. I don't really know how the system works proper to be honest, f1 engine pressure what nots are beyond my small brain
. And even if there is, aero is king remember. We've got silly suspension geometries and high angle driveshafts sprouting up just for aero performance so if the backpressure only costs a few horses then I suppose its worth it... hell if there was no limits on diffuser sizes we would probably have engines mounted 2ft in the air just so it could have massive venturi tunnels
