On our Kenworth and Volvo tractors the exhaust pipe is within inches of our fiberglass air dams and has not been an issue. The DPF is down below the frame though so it has some time to cool before it gets to the outlet of the exhaust pipe. It is my understanding that the regen is confined with the DPF. They do caution us if doing a manual regen while parked not to be parked over grass.
