Introduction
Removing the DPF lets your diesel deliver maximum power and torque while keeping emissions hardware turned off for off-road and competition use. We at EGR Performance know that the "best" DPF delete kit is never one-size-fits-all. It must match your exact model year, engine platform, cab style, and intended application.
The best DPF delete kit for 6.7 Cummins, Powerstroke, and Duramax trucks is a complete year-specific EGR Performance all-in-one bundle that removes the DPF and EGR cooler, installs 4- or 5-inch stainless delete pipes, adds full EGR block-off plates, eliminates the DEF/SCR system, and includes a pre-calibrated ECM flash tune for unrestricted exhaust flow and safe engine operation.
That is why we built and sell the complete, year-specific bundles that combine high-flow delete pipes, full EGR block-off plates, DEF/SCR removal hardware, and ready-to-flash ECM calibration.
EGR Performance has the best all-in-one bundles. Flo-Pro is the best exhaust pipe builder, and Sinister Diesel is the best EGR hardware manufacturer.
This guide walks through every decision to help you find the best DPF delete kit. Follow it to compare EGR Performance, Flo-Pro, and Sinister Diesel by fitment, components, reliability, and buyer value. Keep in mind that these parts are legal only for off-road or competition use.
What Is a DPF Delete Kit?
A DPF delete kit removes the factory DPF, then replaces them with high-flow pipes so exhaust flows freely while the ECM is recalibrated for the new unrestricted flow path.
Eliminate Clogged Filters and Limp Mode Permanently.
Tired of failed regeneration cycles, high exhaust gas temperatures, and restricted power when towing? Our DPF Delete Kits from EGR Performance are precision-engineered for Powerstroke, Cummins, and Duramax platforms. Built with heavy-duty mandrel-bent tubing and robust mounting hardware to handle extreme off-road and competition workloads without missing a beat.
Shop DPF Delete Kits→The DPF normally traps soot and particulate matter from your exhaust. This filter becomes clogged over time and causes fuel economy to suffer due to regeneration cycles.
As diesel engines accumulate operating hours, incomplete active regenerations can leave unburned soot and ash trapped in the filter channels, causing severe exhaust restriction and limp mode.
Learn how to diagnose differential pressure sensor errors and clogged filter cores in our guide on DPF regeneration failure causes.
An off-road DPF delete kit addresses that issue. A DPF delete kit is a set of parts that remove or bypass your Diesel Particulate Filter.
A physical exhaust bypass removes the restrictive ceramic honeycombs inside the factory filter, stopping high-temperature exhaust backpressure at the turbocharger outlet.
To explore how removing these exhaust traps alters backpressure dynamics and engine air-fuel ratios, read our detailed technical overview on what is a DPF delete.
System Component Breakdown
Most kits fall into several types:
- Exhaust-only delete pipes
- EGR block-off plates and hardware
- Complete EGR and exhaust systems bundled together
- ECM Flash Tuning Support
Every kit starts with the delete pipe itself—usually 4-inch or 5-inch stainless steel or aluminized. Next come EGR block-off plates that seal the EGR cooler lines and the EGR valve ports. Full systems also include DEF/SCR removal hardware so you can eliminate the entire liquid system.
Finally, every serious kit includes an ECM flash tune that adjusts fuel maps, boost control, and timing so the engine runs safely on the new flow path.
Configuration Requirements
The parts you need depend on your specific engine, model year, cab/chassis configuration, whether the truck is a pickup or cab-and-chassis, and intended use.
Pipes, hangers, sensor ports, and flange locations change dramatically between 2007.5 and 2024 Cummins, 2011 and 2024 Powerstroke, and LMM/LML/L5P Duramax.
Buying piecemeal parts means guessing and dealing with fitment headaches. A complete year-specific bundle eliminates those risks. Begin there, and then compare brands.
Why Truck Year and Engine Platform Matter Most
Choose a DPF delete kit that matches your exact year and engine code because pipe routing, EGR block-off locations, and tuner compatibility all change between 2007.5-2009, 2010-2012, 2013-2018, 2019-2024+ for the 6.7 Cummins, 2011-2016, 2017-2019, and 2020-2024+ for the 6.7 Powerstroke, and LMM, LML, and L5P for Duramax.
The parts are determined by the year and engine platform of your truck. Exhaust routing, hanger locations, flanges, and sensor ports vary from year to year.
What fits a 2013 Cummins may not clear a 2020 truck or a cab-and-chassis. Same for Powerstroke and Duramax platforms. Always match your kit to your engine's code and date of manufacture.

Skipping this step is the most common mistake truck owners make.
What Should a Complete DPF Delete Kit Include?
A complete DPF delete kit includes a 4- or 5-inch delete pipe, EGR block-off plates for both cooler and valve, DEF/SCR removal hardware, and an ECM flash tuning package so the engine runs safely with unrestricted exhaust flow.
There are six major components to a complete DPF delete kit. Failure to have all of them will lead to fitment or tuning issues.
- Delete Pipe / Exhaust Section: Select a 4" or 5" straight pipe. Aluminized steel is not as durable as stainless steel.
- EGR Delete Hardware: Block-off plates, cooler hardware, reroute. These prevent soot from accumulating in the intake.
- DEF / SCR Removal Hardware: This is a high level bypass of the liquid urea system. It takes out the DEF sensors and plumbing.
- ECM Flash Tuning Support: All kits require a diesel dpf delete tuner for flashing the ECM. This clears fault codes and disables regeneration cycles.
- Optional Extras: Premium bundles include upgraded clamps, gaskets and downpipes. These small components enhance long-term reliability.
- Pickup vs. Cab & Chassis: Check the bed length and chassis type before ordering. There are differences in fitment between these two types of trucks.
Why a Complete Kit Is Better Than Buying Parts Separately
- Matched components save installation time and guesswork.
- A DPF delete kit with tuner bundle ensures your tuning and sensors are in sync from the start.
- Full bundles provide single-source support and warranty coverage.
- Year specific kits eliminate the problem of mismatched, piecemeal parts.
