DPF Delete Pipes

Quick Answers: DPF Delete Pipes

• What is a DPF delete pipe?

  A DPF delete pipe is a straight-through exhaust section that replaces the Diesel Particulate Filter and Diesel Oxidation Catalyst in the exhaust stream. Instead of forcing exhaust through a ceramic filter designed to trap soot, the delete pipe provides an unrestricted flow path. It is mandrel-bent to maintain consistent diameter through bends and flanged to the OEM inlet and outlet specs.

• What is a 6.7 Powerstroke DPF delete pipe?

  A 6.7 Powerstroke DPF delete pipe replaces the mid-section of the exhaust that contains the OEM DPF and DOC canisters. The pipe must match the OEM inlet flange on the downpipe and the outlet diameter feeding the tailpipe section. Third-gen 6.7 trucks (2017-2019) use a different DPF canister diameter than first- and second-gen trucks, so confirm your generation before ordering.

• Does an L5P need a specific DPF delete pipe?

  Yes. The L5P Duramax uses a vertically-mounted DPF and DOC canister arrangement that differs from the LML and LMM packaging. The delete pipe must be fabricated to accommodate the specific inlet angle, and outlet position of the L5P's aftertreatment housing. A universal pipe or a pipe built for an older Duramax will not fit without significant rework.

• Can I run a DPF delete pipe without removing the EGR?

  You can, the two systems are mechanically independent. Some owners delete the DPF first for exhaust flow and address the EGR separately. You can unplug the EGR sensors to avoid the EGR from activating if you plan on doing the delete at a later date after the tunes are installed.

• What is an EcoDiesel delete pipe?

  An EcoDiesel delete pipe replaces the DPF and DOC section on the 3.0L VM Motori exhaust system used in the Jeep Wrangler and Gladiator. The 3.0 EcoDiesel has a compact exhaust layout with tight packaging under the body the delete pipe must be designed for the specific routing constraints of the JL Wrangler or JT Gladiator chassis, not a generic diesel pipe.
