How a DPF Delete Kit Can Boost Your 2022 Ram 2500 Cummins Performance

How a DPF Delete Kit Can Boost Your 2022 Ram 2500 Cummins Performance


Contents [ hide ]

For owners of 2019-2022 Ram 2500 and 3500 trucks with the 6.7L Cummins diesel, installing a DPF delete kit can unlock significant performance potential. This comprehensive guide explains how removing the restrictive diesel particulate filter can increase power, improve fuel economy, and reduce maintenance costs on your heavy-duty truck.

Performance Benefits of DPF Removal

Eliminating the DPF system from your 6.7L Cummins provides multiple advantages:

  • 30-50HP increase from reduced exhaust backpressure
  • 3-5MPG improvement in fuel economy
  • Eliminates regeneration cycles that waste fuel
  • Reduces EGTs (exhaust gas temperatures)
  • Prevents costly DPF failures ($3,000+ replacement)
  • Improves throttle response and turbo spool time
  • Enhances engine sound with deeper exhaust tone

⚠ Important Legal Note: DPF removal is illegal for vehicles driven on public roads in the United States. This information is for off-road use only.
