If you own a Ram truck with the powerful 6.7L Cummins diesel engine, you may have heard about "delete kits". These diesel delete kits are popular for making your truck run better, but choosing the right one can feel tricky.
This simple guide breaks down: what's the best delete kit for 6.7 Cummins? and what to look for so you can find the best choice for your truck.
Why Consider a Delete Kit for the 6.7 Cummins?
Modern diesel trucks have parts to reduce pollution. These parts are the DPF (Diesel Particulate Filter), EGR (Exhaust Gas Recirculation), and DEF (Diesel Exhaust Fluid) systems.
While good for the air, these parts can cause problems for your engine, such as:
- Less power.
- Worse gas mileage (MPG).
- Expensive repair bills when they get clogged or break.
A delete kit removes or bypasses these parts. It lets your engine breathe better and run cleaner.
The main benefits people want are:
- More Power: Your engine can work at its full strength.
- Better Fuel Economy: Many drivers see a few extra miles per gallon.
- Less Maintenance: You stop having problems with the DPF and EGR getting clogged.
Key Features when choosing a 6.7 Cummins Delete Kit
Here are some things you should consider when picking a 6.7 Cummins delete kit:
Fitment: Make sure the kit matches your truck year and model (for example, 2013-2018 Ram, or 2019+ etc).
Scope of delete: Some kits delete just the EGR (exhaust gas recirculation) system, some delete the DPF (diesel particulate filter), some are “all-in-one” and include tuner + delete parts.
Included tuning: If you remove emission parts, your engine management often needs a tune to run properly and avoid errors. Many kits include a tuner.
Support & instructions: Good brand support and installation guide help a lot. As Spetuner, we offer the installation guide, you can check: SPETUNER INSTRUCTION GUIDE>>>
Top 5 Best Delete Kits for 6.7 Cummins (2025 Update)
Finding the right delete kit is simple when you know what you need. Not everyone wants the same thing!
Here are the best 5 types of delete kits for your 6.7 Cummins:
1. Full Delete Kit + Tuning
This is the most common and powerful choice. It removes all of the main emissions parts: the EGR, the DPF, and the DEF system.
For whom: Best for Max Power and Reliability
What You Get: All the needed pipes and plates, plus a diesel tuner.
Why It Wins: By getting rid of all restrictions, your engine breathes easiest. The tuner makes sure the computer works perfectly with the new parts. This setup gives you the biggest jump in horsepower and the best fuel economy.
2. Race-Spec Full Delete Bundle
If you use your truck for competition or extreme pulling, this is the top choice. It takes the full delete to the next level.
For whom: Best for Extreme Performance
What You Get: High-flow exhaust system and plates, along with special, high-power tuning files.
Why It Wins: It is made to handle the highest horsepower tunes. This kit is for builders who want to unlock every bit of power from their 6.7L Cummins engine.
3. DPF and SCR (DEF) Delete Only Kit
If you want to stop your Cummins annoying DPF filter issues and use DEF fluid but want to keep the EGR system, this is a good middle ground.
For Whom: Best for Fixing Maintenance Issues
What You Get: Pipes that replace the DPF and a system bypass for the DEF.
Why It Wins: It ends the costly filter cleanings and "Regen" cycles. Your truck will run cleaner without the DPF, and you won't need to refill Diesel Exhaust Fluid.
4. EGR Delete Only Kit
The EGR system can put dirty, hot exhaust back into your engine. An EGR delete solves this problem.
For whom: Best for Engine Health
What You Get: Block-off plates and a bypass hose for the EGR cooler.
Why It Wins: This kit helps your engine live longer. It stops carbon (soot) buildup inside the motor. This is a smart choice for truck owners who live in areas where some emission parts must stay on the truck.
5. High-Flow Exhaust System
If you are not ready for a "delete" but want better sound and a little more power, look at a full exhaust upgrade.
For whom: Best for Better Air Flow and Sound
What You Get: A larger, better-made exhaust pipe (4-inch or 5-inch) that goes from the turbo all the way back.
Why It Wins: This pipe lets the exhaust gas escape faster than the factory pipe. It gives a deeper, throatier sound and improves performance just by letting the engine breathe easier.
