It's not stock, and not needed.   The stock overflow was routed straight 
down, where it could fizz water onto the ground in front of the right rear 
tire.   (In fact, I know of a Pantera in the UK that recently spun rather 
dramatically because the owner failed to address this--he had 'topped off' his 
cooling system before going out on the track and soon found himself spinning 
out!).

At a minimum, the stock overflow hose should be replaced with a long hose 
routed out the back of the car, beyond the tires.   Having a second overflow 
tank is definitely overkill, but it's certainly not a bad thing.
