There is still a restriction in the exhaust, the motor just doesn't do this on its own, A lot of cars have what is called a mass air flow valve in the exhaust, they stop working and backs up the exhaust heat in the system, just like a catalytic will when they get plugged. I assume there is nothing crushed on the exhaust system?
