About DPF and DPF Delete

Most post-2007 diesel vehicles are equipped with a Diesel Particulate Filter (DPF) for emissions. Removing the DPF can ease fuel flow and increase overall fuel mileage due to reduced backpressure and maintenance requirements.


Installation takes about 1 hour with basic hand tools. Quicker with an automotive-style lift. Cutting may be needed for shorter wheelbase bed/cab configurations. Includes clamps, hangers, and hardware, with possible reuse of some factory hardware.

Tuner Requirement

Removing the DPF, CAT, SCR, and/or DOC requires a tuner capable of DPF delete to avoid check engine lights or diagnostic trouble codes.


  • Significant increase in fuel mileage is expected.
  • Removal of DPF/CAT can lead to a combined mileage of 18-19 mpg.
  • Eliminates the need for regular DPF servicing (cleaning, replacement).
  • Reduces the risk of costly DPF failures.
  • Decreased exhaust backpressure enhances engine performance.
  • An ECU remap along with a DPF delete can increase power and torque for all vehicles.
