Muffler and Cat DELETE Pipe Kits

DPF and DPF Delete

Most post-2007 diesel vehicles are equipped with a Diesel Particulate Filter (DPF) for emissions, but this comes with drawbacks such as constant maintenance and repairs. Removing the DPF can ease fuel flow, thus increasing overall fuel mileage.


Installation takes about 1 hour with basic hand tools. It may be quicker with an automotive-style lift. Cutting may be required for shorter wheelbase bed/cab configurations. Includes clamps, hangers, and hardware, though some factory hardware may need to be reused.

Tuner Requirement

Removing the DPF, CAT, SCR, and/or DOC requires eliminating emission-related sensors. A DPF delete capable tuner is necessary 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 from the typical 13-14 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.
