Exhaust gases move through a structured substrate that traps particulate matter while allowing flow to continue. Over time, collected soot is burned off during regeneration, clearing the filter for continued use. A restricted filter can affect exhaust pressure and engine response. Exhaust filtration remains balanced with the Cummins 5579375 managing both capture and flow.
