The 6.7L Cummins is a powerhouse, but stock parts like the DPF are holding it back. Now, imagine if ditching that DPF not only cranked up your truck’s power but also boosted your fuel economy. Yeah, that’s right. Removing the DPF (and the EGR) lets your truck breathe a whole lot easier. Those factory parts just recycle exhaust fumes, which eventually leads to that nasty soot buildup.
Top Benefits of a DPF Delete for Your 6.7 Cummins Engine
Removing the DPF from your 6.7 Cummins engine offers a range of significant benefits:
- Enhanced Fuel Efficiency: By eliminating the DPF, your engine will consume less fuel, translating into noticeable savings at the pump.
- Improved Engine Performance: A DPF delete facilitates better airflow, leading to increases in horsepower, torque, and throttle response.
- Lower Maintenance Costs: Without the DPF, you can avoid the expense and hassle of frequent cleanings and replacements.
- Extended Engine Longevity: Removing the DPF reduces the risk of damage caused by excessive back pressure and heat, contributing to a longer-lasting engine.

Step-by-Step Guide to the 6.7 Cummins DPF Delete Process
Many enthusiasts have requested a comprehensive guide to the Bluetec system on the 6.7 Cummins. It’s high time we consolidate this information into one detailed resource for those seeking to understand or remove their emissions hardware. While this overview is extensive, it’s designed to be both informative and practical. Let’s dive into the basics.
The Bluetec system on the 6.7 Cummins comprises several key components that enable the engine to comply with 2010 EPA emissions standards. On the engine side, you’ll find the EGR (Exhaust Gas Recirculation) system. On the exhaust side, the system includes the DPF (Diesel Particulate Filter), the NOX canister (for scrubbing oxides of nitrogen), and the catalytic converter.
Exhaust System Breakdown
Examining the exhaust system from the turbo to the tailpipe, you’ll encounter four primary canisters:
- Catalytic Converter: Positioned closest to the turbo, this long canister is located in the bend of the downpipe.
- NOX Filter: The first large round canister, responsible for reducing nitrogen oxides.
- DPF: The third canister, crucial for filtering diesel particulates.
- Muffler: The final canister, designed as a straight-through unit for those curious about its construction.
Sensors and Monitoring
The factory exhaust setup includes five sensors:
- Two oxygen sensors, larger in diameter.
- Three temperature probes that monitor the DPF’s temperature to trigger regeneration as needed.
- A stainless steel tubing assembly connects to rubber tubing and a pressure sensor on the passenger side of the transmission. This DPF differential pressure sensor measures exhaust flow through the DPF and evaluates particulate matter levels, working in tandem with the temperature probes to maintain optimal DPF function.
Engine Side Components
Under the hood, the Bluetec system is divided into three main sections:
- EGR (Exhaust Gas Recirculation): Located atop the intake horn, with a brown servo motor mounted to its right.
- Throttle Valve: Positioned on the driver’s side of the intake horn, containing the butterfly valve.
- EGR Cooler: Mounted on the passenger side of the intake, above the exhaust manifold.
EGR System Operation
The EGR system introduces exhaust gases into the intake stream via the crossover tube, which runs between the valve cover and the radiator. This tube connects the EGR Cooler to the EGR. As the EGR opens, hot exhaust gases flow through the crossover tube and into the intake. The EGR Cooler aims to reduce the temperature of these exhaust gases using the engine’s cooling system. The throttle valve regulates the mix of fresh air and exhaust gases entering the intake. With the EGR system in place, your engine often runs on hot, sooty exhaust gases rather than clean, fresh air.
For a visual reference, here’s an illustration showing the basic locations of these under-hood components. Note that the crossover tube and EGR servo motor are removed in the picture, but it provides a clear comparison to the stock setup.
To carry out any emissions deletes on your 6.7 Cummins, using an aftermarket tuner is essential. Among the top choices for this job is the Mini Maxx V1, known for its effectiveness in reprogramming the engine’s ECU.
It’s important to note that any modifications, including hardware removal or programming changes, could potentially void your warranty. The impact on your warranty largely depends on your local dealership’s policies and your relationship with them.
If you’re still under warranty, my recommendation is to have Dodge address any issues with the emissions system before proceeding with a delete. This ensures the system is functioning properly, so when you do perform the delete, you can start with a clean slate. For those without warranty coverage, engaging with online forums can provide valuable insights and assistance from experienced enthusiasts.
Additionally, be sure to check your local regulations regarding emissions testing. Understanding these rules beforehand will help you avoid any legal complications.
If you decide to go through with the delete, you might just find yourself wondering, “Why didn’t I do this sooner?”
