Why Consider a DPF Delete?
What is a DPF (Diesel Particulate Filter)?
A Diesel Particulate Filter (DPF) is designed to trap soot and fine particles from your diesel engine’s exhaust to help reduce emissions. While effective for emissions control, DPFs are known to clog easily—especially during city driving or short-distance trips where regeneration cycles can’t complete properly.
Common Problems with DPF Systems:
- Frequent Regeneration or Cleaning: DPFs often require forced regeneration or professional cleaning, adding to your maintenance time and costs.
- Loss of Power: A clogged DPF creates excessive backpressure, reducing engine performance and fuel efficiency.
- Warning Lights & Error Codes: A failing or clogged DPF can trigger dashboard alerts, limp mode, or failed inspections—disrupting your driving experience.
A DPF delete can help eliminate these issues by improving exhaust flow, lowering EGTs, and restoring lost power—making it a popular choice for off-road and performance applications.

Installation:
Installation typically takes about 1 hour using basic hand tools and can be done on the floor of your driveway or garage. Using a car lift may be faster. For vehicles with shorter wheelbase bed/cab configurations, some cutting may be required. This includes clamps, hangers, and hardware, but you may need to reuse some of the stock parts.
Deleting the DPF, CAT, SCR, and/or DOC requires eliminating emissions-related sensors. To avoid triggering a Check Engine Light or Diagnostic Trouble Code, a tuner with DPF Delete capability must be used.
