Huh!?!
 
How does the exhaust get sucked forward? If the car is moving forward there  
will be sufficient airflow over the deck lid to prevent any exhaust from 
flowing  forward. If the car is still, the chance of exhaust flowing forward is the 
same  if the exit is in the rear or the side. Now if the car is going 
backward, now  you might be able to get some exhaust into the inlet.
