DPF/DEF/EGR Delete 2013-2018 Ram 6.7L Cummins All-in-One Kit

Key Features

Dodge Ram 6.7L Cummins Diesel is a beast of an engine, but factory emissions controls—DPF, EGR, and overly conservative tuning—hold it back. Deleting these systems unlocks real performance, efficiency, and engine longevity while eliminating common headaches:

• No More DPF Regens – Stop wasting fuel on forced burns and avoid costly DPF failures.
• End EGR Clogging – Prevent soot buildup in your intake, keeping your turbo and valves cleaner.
• Unlock Hidden Power – The factory tune strangles your engine—free it with optimized fueling and airflow. Expect 80-150+ HP gains (depending on tune)
• Better Fuel Economy – Expect 1-3 MPG improvements with proper tuning.
• Lower EGTs – Critical for towing heavy loads without overheating.
• Longer Engine Life – Less heat stress, cleaner oil, and reduced turbo wear.

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)
