DPF/EGR Delete Kit for 2013-2018 Dodge Ram 6.7 Cummins

This DPF/EGR kit for the 2013–2018 6.7L Cummins is designed to replace the problematic factory emissions system, boosting horsepower, torque, and fuel efficiency. By removing the failure-prone DPF and EGR components, it delivers smoother throttle response, lowers engine bay temperatures, and eliminates forced regenerations.

Key Features

Significant Performance Gains: Experience a dramatic increase in horsepower and torque, along with improved throttle response and elimination of turbo lag.

Enhanced Fuel Economy: By removing the restrictive exhaust filtration and stopping the fuel-intensive regeneration cycles, you can see MPG improvements of 2-5 MPG.

Improved Engine Longevity: Eliminates EGR soot and carbon recirculation, reducing carbon buildup on intake valves and pistons. Lowers Exhaust Gas Temperatures (EGTs) for a healthier, longer-lasting engine.

Premium Construction: All pipes and components are constructed from heavy-duty, T409 stainless steel for superior corrosion resistance and durability.

Simplified Maintenance: Drastically reduces the cost and complexity of future maintenance by removing the most expensive and failure-prone parts of the emissions system.

Tuner Required for Installation: Installing a delete pipe requires more than just swapping out hardware. When removing of the DPF, CAT, SCR, and/or DOC involves removing and eliminating emission related sensors. A DPF delete capable tuner is required to prevent any check engine light or diagnostic trouble codes from setting.

How to Choose a DPF Delete?

4” vs 5” DPF Delete Pipe Comparison

• 4-inch Pipe: Produces a tighter, raspier exhaust note—especially noticeable at lower RPMs. Ideal for daily driving or mildly tuned trucks where excessive drone is undesirable.
• 5-inch Pipe: Delivers a deeper, more refined tone with less high-pitch resonance. Better suited for high-output builds and towing applications, where improved exhaust flow is beneficial.

Driver Feedback Summary

• The 4" pipe works well for stock or lightly modified trucks and a quieter cabin.
• The 5" pipe is perfect for aggressive builds, deep-tone enthusiasts, and those maximizing exhaust performance.

Types of DPF Delete Kits

DPF Race Delete

• Removes only the DPF (retains stock downpipe)
• Offers minimal performance gains but is the most budget-friendly
• Best for cost-conscious users or avoiding emissions testing

Downpipe-Back Delete

• Replaces the exhaust from the turbo downpipe back
• Improves mid-range power and throttle response
• Ideal for street builds using the stock turbo

Turbo-Back Delete

• Full system replacement starting from the turbo outlet
• Includes a high-flow downpipe for maximum efficiency
• Reduces turbo lag and boosts top-end power
• Top choice for tuned or high-performance engines

Dual Exit (5" only)

• Splits into dual exhaust paths
• Enhances cooling and flow for extreme conditions
• Commonly used in heavy towing or competition setups

Muffler vs. No Muffler

With Muffler

• Reduces exhaust noise for daily driving
• Slight power restriction (~5–10 HP)
• More likely to comply with local noise regulations

Straight Pipe (No Muffler)

• Loud, aggressive exhaust tone
• Unrestricted flow for maximum horsepower
• Often not street-legal due to noise and emissions rules
• Intended for off-road or race use only

FAQs

Q: Can I revert my truck back to stock after a delete?
Yes. As long as you keep all OEM emissions parts (DPF, EGR, SCR) and have a backup of your original ECU file, you can reinstall the components and flash the stock calibration.

Q: Do I need tuning software after installing the delete kit?
Yes. Custom tuning is required to disable DPF/EGR systems in the ECU. Without a proper tune, your truck will throw error codes, run poorly, or enter limp mode. Tuner is included in this kit.

Q: Will I pass emissions testing after the delete?
No. Any vehicle with emissions systems removed or disabled will fail emissions or visual inspections in regulated areas. Delete kits are intended for off-road or competition use only.

Q: Is the DPFExhaust delete kit hard to install?
Installation is beginner-to-intermediate level for most DIYers. DPF delete is straightforward, while EGR components can be tricky due to seized or brittle bolts—professional help may be needed.

Q: How much horsepower/torque can I gain?
Tune-dependent, but typical gains:

• Stock Turbo: +80-150 HP / +150-250 lb-ft
• Upgraded Turbo: +150-250+ HP / +300-400+ lb-ft (with supporting mods)
