Muffler delete

Recommended Posts

The big muffler box is the SCR box, it’s where it the DEF fluid and exhaust and mixed and lowers the NOX levels. The outlet NOX sensor sniffs the exhaust as it comes out of the SCR box , if the NOX is to high you get the 5MPH derate . So in other words, it has to on there unless you get a delete done.
