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.

Deciding between a DPF & CAT delete pipe and a full exhaust system comes down to how much of the factory exhaust you want gone. The pipe swaps only the mid-section, the canister housing the DPF (diesel particulate filter) and catalytic converter and bolts into the same OEM flanges. The full exhaust runs from the downpipe all the way to the tailpipe instead, worth it if your factory exhaust is rusted out or you want the deeper 5-inch note. Both remove the same restriction; they differ in how much pipe gets replaced.

Fitment runs by engine and generation, not just truck model. Ford's 6.7 Powerstroke alone spans four separate SKUs in this collection 2008-2010, 2011-2016, 2017-2019, and 2020-2022 and Ram's 6.7 Cummins and GM's Duramax (LML, L5P, and LMM canister styles) split by year range the same way. Match your pipe or system to engine and year range, not the badge on the tailgate.

DPF & CAT delete pipes start from $352; full exhaust systems start from $699. Exact pricing depends on which of the 23 engine-specific fitments in this collection matches your truck Ford Powerstroke, Ram Cummins, GM Duramax, Nissan Titan Cummins, and Ram EcoDiesel are all covered.

None of this is DEF (diesel exhaust fluid) or SCR (selective catalytic reduction) hardware. This collection is exhaust piping DPF and DOC canister replacement only and nothing sold here touches, bypasses, or removes any DEF/SCR component. If you're searching for a DEF delete kit, that's not what's stocked in this collection.

A delete pipe alone usually trips a check-engine code, since the factory sensors expect a DPF and DOC in the exhaust path. Pairing it with a tune a separate purchase from a different collection is how most owners clear those codes and keep the truck running clean.
