NO, you definitely do not need th eheatshield in order for the car to run. However, it was put there for a reason. Th ecatalitic converter gets EXTREMELY HOT when you drive, and the heat shield was put in place so that the hear will not transfer into the cabin. I have removed my heatshield about 2 years abo because it was rusting away and making noise. The only thing I notice now is that the floor of the car, right above where the cat is gets warm when I drive for a long period of time.
