Ram Cummins Delete Kits & Performance Parts

The best kit depends on your truck’s generation and goals. If you’re wondering what is the best delete kit for 6.7 Cummins, it usually means a full bundle with DPF, CAT, and EGR removal with DPF, CAT, and EGR removal plus a tuner for the most reliable performance gains. 

For 2013-2024 models, updated EFI Live, EZ Lynk, or RaceME-based kits are optimized for modern ECMs and offer higher power levels with better transmission control.

A complete kit usually includes:

• DPF & CAT delete pipes or a full 4-5″ exhaust system
• DEF delete Cummins components for full emissions removal
• EGR valve and cooler delete kit
• Tuner with selectable power levels for on-the-fly adjustments
• All required hardware and installation instructions

These components work together to eliminate factory emissions restrictions and improve airflow, throttle response, and fuel efficiency while keeping exhaust gases flowing freely.

A full bundle ensures compatibility between parts, balanced airflow, and optimized tuning for your exact model year. Buying components individually can lead to calibration mismatches, CEL codes, or reduced performance.

Compatibility is based on engine generation rather than trim.

• 2007-2012: First-gen 6.7L Cummins
• 2013-2018: Updated ECM with different sensor layout
• 2019-2024: Newer emissions architecture and electronic control modules (ECM swap may be required for 2022-2024)

Both 2500 and 3500 models share the same core fitment - choose the correct kit for your year range.

The difference mostly comes from electronics and tuning, not the exhaust hardware.

• ECM & Tuning

2019+ Cummins trucks have a newer ECM with stronger security, so they need specific tuning setups and sometimes an ECM swap.
2013-2018 models are easier to tune directly and work with more basic tuners.

• Power & Setup

2019+ kits support advanced tuners with features like Switch-On-The-Fly power control and transmission tuning, reaching higher HP gains and noticeable boost in overall performance.
Older kits offer simple, proven setups that install faster and perform reliably.

In short:
2019+ kits are for newer electronics and more tuning flexibility.
2013-2018 kits are simpler, plug-and-play, and still deliver strong performance.

• Reduces intake carbon buildup
• Lowers operating temperatures
• Prevents clogging and turbo damage
• Improves throttle response and fuel economy

Yes. Without tuning, the ECM will still expect emissions components to be active, triggering error codes and limp mode. A tuning device disables those parameters, optimizes fuel and timing maps, and can add power gains up to +150 HP depending on setup.

Choose 4″ systems for moderate upgrades; 5″ for maximum flow and sound. Muffler options balance tone and noise control - straight-pipe setups deliver the most aggressive exhaust note. 

You can also add a grid heater delete or intake manifold upgrade for even better airflow and cooler intake temps.

• DPF clogging and forced regenerations
• EGR cooler leaks and soot buildup
• Power loss from backpressure
• Frequent check-engine lights and reduced mileage

Professional installation takes around 6-10 hours, depending on the setup and whether it includes a full exhaust replacement or just DPF/EGR removal. Every kit is designed to be easy to install with detailed instructions.

Delete kits are intended for off-road, competition, or export use only. Removing emissions systems on public road vehicles violates EPA and Environment Canada emissions regulations.
