6.7L Cummins Diesel DEF Delete Kit for 2010-2014

Comparing 6.7L Cummins DEF Delete Kit Configurations

Kits That Include a Diesel Muffler

Several options in this collection pair a 4-inch delete pipe with an inline diesel muffler. This setup produces a moderate exhaust tone during off-road use without an additional purchase.

Kits That Bundle a Tuner Module

When the truck’s ECM needs adjusted after removing emissions hardware, a tuner-included kit simplifies the process. Confirm that the tuner supports your specific 2010–2014 6.7L Cummins calibration by checking the product page.

Kits with a CCV Reroute Assembly

One kit adds a CCV reroute to redirect crankcase ventilation. This can cut down on intake buildup under prolonged off-road conditions, but it is not part of every kit.

Engine and Vehicle Compatibility

Every kit in this collection is built for the 2010–2014 Dodge Ram 2500 and 3500 with the 6.7L Cummins diesel engine. Because cab style, transmission type, and emissions hardware can vary, confirm your truck’s exact configuration on the individual product listing.

Frequently Asked Questions About 6.7L Cummins DEF Delete Kits

What exactly does a 6.7 Cummins DEF delete kit include?

Kit contents vary by SKU. Most include delete pipes and block-off plates to remove the DEF, EGR, and DPF hardware. Some add a diesel muffler, a tuner module, or a CCV reroute assembly. Review the individual product page to see exactly what is supplied and confirm the components match your off-road needs.

Will these kits fit my 2010-2014 Dodge Ram 2500 or 3500?

All kits are designed for the 2010-2014 Dodge Ram 2500 and 3500 with the 6.7L Cummins diesel engine. Because cab style, transmission, and emissions hardware can differ, check the product page fitment details and look up your truck’s exact configuration before ordering.

Is a tuner required to delete the DEF system on a 6.7L Cummins?

Not necessarily. Some kits ship without a tuner, focusing on the mechanical removal only. Kits that include a tuner adjust the ECM to prevent diagnostic messages after the hardware change. If your chosen kit does not include a tuner, you may need to obtain compatible tuning separately. Confirm requirements on the product page.

What is the difference between a kit with a muffler and one without?

Kits that include a diesel muffler moderate the exhaust tone during off-road operation. Kits without a muffler deliver a louder, more direct exhaust note. The choice depends on your preference for off-road noise levels. Check the product description to see which option fits how you plan to use the truck.

Are these DEF delete kits legal for highway use?

No. These products are intended exclusively for off-road use. Removing emissions equipment may violate federal, state, and local laws for on-road vehicles. Before purchasing, verify all applicable regulations in your area and on the properties where you intend to operate the vehicle.

Do I need to reprogram my truck’s computer after installing a DEF delete kit?

If the kit includes a tuner, that module typically handles the necessary calibration changes. Without an included tuner, you might need separate programming to clear warning lights and adjust engine parameters. Look at the tuner specifications on the product page and, if needed, consult a tuning specialist for your truck’s specific calibration.

What is a CCV reroute, and why is it part of some kits?

A CCV (crankcase ventilation) reroute redirects blow-by gases away from the intake, helping reduce oil and carbon buildup under sustained off-road use. Only one kit in this collection includes a CCV reroute assembly. If that feature matters to you, verify it is listed in the kit contents before placing your order.

How can I tell which kit is right for my off-road setup?

Start by deciding whether you want a muffler, tuner, or CCV reroute included. Then compare the kit contents on each product page. Consider your typical off-road conditions and how much exhaust tone is acceptable. The product descriptions show exactly which pipes, plates, and optional components come in each bundle.

How do I verify correct fitment before ordering?

Match your truck’s engine (6.7L Cummins), model year (2010-2014), and cab configuration against the fitment notes on the product page. Pay attention to transmission type and any existing modifications. If you are unsure, reach out through the Contact Us page during business hours to ask a product specialist for guidance.

Unused products may be returned within 45 days of delivery when the Return & Exchange Policy conditions are met. Return shipping responsibility depends on the reason for the return.
