The 6.7 Cummins engine is a powerhouse of performance and durability, trusted by truck owners, off-roaders, and heavy-duty haulers alike. Found primarily in Ram 2500 and 3500 models, this engine delivers impressive torque and towing capabilities. However, the Diesel Particulate Filter (DPF) system, part of modern emissions equipment, often poses challenges for truck enthusiasts who demand more power and fewer restrictions.
Many 6.7 Cummins owners experience issues like reduced fuel economy, clogged filters, increased exhaust temperatures, and frequent regeneration cycles. Over time, these problems can affect engine performance and add significant maintenance costs. That’s where DPF delete kits come into play.
In this in-depth buyer’s guide, we’ll explore the most reliable DPF delete kits for the 6.7 Cummins engine, including a featured recommendation from DynoVox, insights from user-installation videos, FAQs, and a comprehensive checklist to help you make an informed, confident decision.
What is a DPF Delete Kit?
A DPF delete kit is a performance upgrade that removes the diesel particulate filter and replaces it with a high-flow exhaust component—typically a straight pipe or race pipe. This modification is designed exclusively for off-road or competition use, where emission compliance is not required.
By removing the DPF, you eliminate one of the most restrictive components in the exhaust system. The result? Better exhaust flow, increased horsepower, enhanced throttle response, and reduced turbo lag. Additionally, it eliminates the need for DPF regeneration cycles, which can be time-consuming and fuel-wasting.
Why Choose a DPF Delete Kit?
1. Improved Fuel Efficiency
The factory DPF traps soot and forces the engine to burn more fuel to clean it during regeneration. Removing it can result in a 10–15% increase in fuel mileage, especially during long hauls or towing.
2. Enhanced Engine Performance
DPF systems create exhaust backpressure, limiting engine efficiency. A delete kit opens the exhaust system, allowing the turbocharger to spool faster and increase torque. Many users report gains of 30–100+ HP when paired with proper tuning.
3. Lower Maintenance Costs
DPF filters can clog, leading to expensive replacements and downtime. Deleting the DPF removes the need for filter replacements, sensors, and DEF fluid refills, saving thousands of dollars over time.
4. Better Sound and Driving Experience
Many Cummins owners enjoy the deep, aggressive exhaust note that comes with a DPF delete kit. It also removes the heat and smell associated with active regenerations.

Frequently Asked Questions (FAQs)
Is it legal to install a DPF delete kit?
In the U.S. and Canada, it is illegal to remove emissions equipment for on-road vehicles under EPA and CARB regulations. However, DPF delete kits are legal for off-road, competition, or agricultural use only. Always verify local laws before purchasing or installing.
Do I need a tuner with a DPF delete kit?
Yes. A tuner is mandatory. The ECM (Engine Control Module) must be reprogrammed to recognize the absence of emissions components. Without tuning, your truck will throw codes, go into limp mode, or fail to start.
Can deleting the DPF damage my engine?
No—provided the delete is paired with proper tuning and quality components. In fact, deleting the DPF often reduces EGT (Exhaust Gas Temperatures) and soot buildup, potentially extending engine life in off-road settings.
What is the total cost of a DPF delete setup?
The cost can range from $800 to $2,000, depending on the kit brand, exhaust type (turbo-back or downpipe-back), and tuner. DynoVox offers competitive pricing with premium build quality.
