That was last weekend at the local "C&C" out here in Raleigh (first Sat of every month started and ran by the local Porsche and Ferrari club).... The guy with the headset Ken Vrana was taking sound tracks for his site and cause.... He moved out here a few yr's ago and the is his site.... Nice guy with a cause
My recollection of that exhilarating sound of the whine of the turbos spooling up (and down) is only that pronounced when a car has no cats or muffler(s). :cheers
