Passive Diesel Particulate Filter (DPF) technology provides the highest tailpipe PM eduction available today (>90%), making it a popular choice for retrofit programs. However, passive DPFs are sensitive to exhaust temperature and minimums must be met to ensure consistent and reliable DPF regeneration. The Donaldson LNFand LXF products are designed and verified for select EGR and non-EGR on-road engine applications:

LNF Mufflers for MY 1993-2006 high NOx engines*
LXF Mufflers for MY 2002- 2006 low NOx engines*
