Frequently Asked Questions About 2014 6.7 Cummins DEF Delete Kits

What does a 2014 6.7 Cummins DEF delete kit include?

These kits bundle components to remove the DEF, DPF, and EGR systems on 2010-2014 Ram 2500/3500 trucks. Common parts include delete pipes, a muffler, and block-off plates. Some kits add a tuner or a CCV reroute. Check each product listing for exact contents, as kits vary in pipe diameter and included accessories.

Will this kit fit my 2014 Ram 3500 with the 6.7L Cummins?

The kits in this collection are designed for 2010-2014 Dodge Ram 2500 and 3500 models equipped with the 6.7L Cummins engine. If your truck falls within that range, the kit may fit, but always verify the specific product details and any exclusions. Not all kits include every component for every sub-model.

Do I need a tuner to install a DEF delete kit?

For vehicles that require electronic tuning after emissions modifications, a tuner is necessary to prevent error codes and ensure proper operation. Some kits in this collection include a tuner, while others are pipe kits only. Check the individual product page to see if a tuner is provided, or if you must purchase one separately.

What is a CCV reroute and why is it included in some kits?

A CCV (crankcase ventilation) reroute redirects oily crankcase vapors away from the intake system, reducing carbon buildup. A few delete kits bundle this upgrade alongside the exhaust components. If your kit does not include it, you can often add it separately. Confirm availability on the product page.

Is the muffler included, and will it change the exhaust sound?

Many kits include a diesel muffler to moderate the exhaust note. Without one, the truck may be significantly louder. If quiet operation is important for your off-road environment, select a kit that lists a muffler in the title or description. Check each listing to confirm muffler type—some kits list a 4-inch muffler, while others may offer dual pipes.

Can I install this delete kit myself?

Installation complexity varies by kit and by your mechanical experience. These kits typically involve removing factory emissions components and installing delete pipes, a tuner (if included), and possibly a CCV reroute. Refer to each product page for any installation guidance or requirements. For detailed support, contact us during business hours.

Are these DEF delete kits street legal?

No. These products are intended solely for off-road use and are not compliant with on-highway emissions regulations. Using them on public roads may violate federal, state, and local laws. Always verify your local regulations before purchasing or installing a delete kit.

How do I choose between the different 2014 6.7 Cummins DEF delete kit options?

Focus on what your off-road application requires. Compare pipe diameter (all kits here are 4-inch), inclusion of a muffler for sound control, whether you need a tuner, and if a CCV reroute is desired. Some kits are all-in-one, while others omit certain components. Read each product title and description carefully to match your build.

What is the return policy for delete kits?

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. Review the current policy and use the Contact Us page for assistance. Check the individual product page for any applicable warranty terms.

How do I ensure the tuner will work with my truck?

If the kit includes a tuner, it is typically pre-loaded with files compatible with the 2010-2014 6.7L Cummins platform. However, you may need to confirm your truck’s specific ECU strategy or transmission calibration. Refer to the product page for tuner compatibility details, or reach out through our Contact Us page for pre‑sale questions.
