In 1983 Ferrari in collaboration with a world renowned designer Ermenegildo Zegna offered an unique version of the Ferrari 512 BBi with interior designed by this fashion house.
One of the few options available to the Ferrari GTO (along with radio, air conditioning, power windows and red seat inserts) was an ANSA sport exhaust. The only external difference is in the rear: instead of the standard four exhaust pipes (two on each side) there were only two large expanding pipes, called "Megaphones", due to their characteristic shape.
