The 2013–2021 Ram 6.7L Cummins All-in-One DPF/DEF/EGR Delete Kit is a complete emissions-removal and EFI Live tuning package for supported Ram 2500 and 3500 pickup trucks equipped with the 6.7L Cummins diesel engine. It combines EFI Live AutoCal V3 custom tuning, DPF/DEF delete exhaust components, EGR delete hardware, and the required bypass cable where applicable in one matched package.
The kit is configured specifically for the truck's ECM platform. 2013–2018 Ram 6.7L Cummins trucks use the CME platform, while 2019–2021 trucks use the CMF platform. The supplied EFI Live calibration is matched to the correct ECM architecture so fueling, throttle response, boost control, and overall drivability are calibrated for the selected application after the factory DPF, DEF/SCR, and EGR systems are removed.
Multiple exhaust configurations and four available EFI Live power levels allow the package to be configured around the truck and intended setup instead of combining unrelated tuning and hardware from separate sources.
Note: Off-road and competition use only where permitted. Verify applicable federal, state, provincial, and local emissions regulations before installation.

EFI Live Tuning for 2013–2021 Ram 6.7 Cummins
The package uses the EFI Live AutoCal V3 as the tuning interface. The AutoCal device ships blank, and the custom calibration is prepared after the required vehicle information is submitted.
Tuning is matched to the correct Cummins ECM generation:
2013–2018 Ram 6.7L Cummins: CME ECM platform
2019–2021 Ram 6.7L Cummins: CMF ECM platform
Using a platform-specific calibration is important because the CME and CMF ECM architectures require different tuning configurations. Matching the calibration to the correct truck helps maintain controlled fueling, throttle response, boost behavior, and drivability.
Available EFI Live Power Levels
Stock Power – Calibrated operation without an additional advertised horsepower increase
+65 HP – Mild performance increase
+100 HP – Higher-performance calibration
+130 HP – Highest available advertised power level in this package
Actual vehicle performance can vary based on model year, transmission, supporting modifications, vehicle condition, elevation, fuel quality, and operating conditions.
Exhaust Options
The 2013–2021 Ram Cummins package can be configured with one of three exhaust options depending on the desired system layout:
5-Inch Downpipe-Back Exhaust – Larger-diameter exhaust configuration replacing the applicable factory exhaust section downstream of the downpipe.
4-Inch Downpipe-Back Exhaust – Full 4-inch downpipe-back configuration for the supported Ram pickup application.
4-Inch Stainless DPF Delete Pipe – Stainless replacement pipe for customers who want to retain more of the existing exhaust system.
Select the exhaust option that matches the vehicle configuration and intended installation before ordering.
DPF, DEF and EGR Systems Addressed by the Kit
This package is designed around the three primary emissions systems found on supported 2013–2021 Ram 6.7L Cummins trucks:
DPF – Diesel Particulate Filter: Captures particulate matter in the exhaust and periodically uses regeneration cycles to burn accumulated soot.
DEF/SCR – Diesel Exhaust Fluid / Selective Catalytic Reduction: Uses diesel exhaust fluid as part of the factory NOx emissions-control system.
EGR – Exhaust Gas Recirculation: Routes a controlled portion of exhaust gas back through the intake system as part of the factory emissions strategy.
The supplied EFI Live calibration is configured for the corresponding hardware changes so the ECM is calibrated for the selected setup.

Performance and Operating Characteristics
Removing restrictive exhaust components changes exhaust flow through the system. When paired with the correct calibration and exhaust configuration, the setup is intended to provide a less restrictive exhaust path and calibrated engine operation for the modified hardware.
Reduced exhaust restriction – The selected replacement exhaust configuration provides a freer-flowing path than the factory DPF-equipped system.
No factory DPF regeneration cycles – The modified configuration no longer relies on the original DPF regeneration process.
Selectable tuning levels – Choose an EFI Live calibration appropriate for the intended use of the truck.
Platform-specific drivability calibration – CME and CMF applications receive tuning matched to the appropriate ECM architecture.
Matched components – Exhaust, EGR hardware, tuning, and required accessories are selected as part of one package.

Customer Reviews
Overall rating: 4.7 / 5 from 372 reviews.
Over all I am extremely happy with this kit. Things that need addressing:
You have to ask for the installation instructions for the EGR delete kit to be emailed to you. The EGR kit does not come with the barbed/NPT threaded nipple adapter like other kits do. It also doesn’t have a good locking mechanism to hold the orher end of the heater hose into the junction. (See photos). There for I had to use galvanized wire to secure it because it eventually started to separate even though the plate was holding it together.
The stainless exhaust is awesome. I did the upgraded to 308 stainless and it is high quality! I didn’t have to trim or cut the pieces at all on my short bed mega cab.
Once I figured out how to install the programming into the the tuner that was also pretty easy. Customer service is very good and quick to reply to emails and they are Americans, if you call in.
The egr removal was fairly simple after watching a good YouTube video by dark iron diesel. There’s some really tight areas you gotta reach into. Removing some nuts in weird angles requires some thinking. Had a leak on one of my blocker plates that’s why you see soot on the plate. Changed gasket and flipped it over and no more leak. If you’re any good with your hands you’ll be okay.
Received my 2019 Ram 2500 complete delete kit in 5 days from ordering, all parts arrived undamaged. The install was not too complicated assuming you have some mechanical abilities and are comfortable tearing your truck apart. Highly recommend shorty 15mm for one of the bolts on the EGR elbow on the front of the engine, that was the biggest pain out of everything. My truck sounds amazing now!! I could not believe how much better the truck drives and sounds. Customer service was super responsive as well, I reached out several times with a few questions along the way from ordering to install and they responded quickly and with the information I needed. I would definitely order from them again.

Absolutely loving this kit! Truck sounds like a real diesel now.. Everything came within 3-4 days, installation was super easy if you follow all directions provided. Had a few questions regarding installed mods on the truck, support and the tuner were very helpful!
I ordered my kit about a year ago and finally got the courage to install it. I had one moment of panic while programming the ECU. The flash didn't take and after reaching out to the support team, I overlooked the bypass wire instructions for my year truck. After swapping the wires, everything went smoothly. I ordered just the delete pipe and it fit perfectly without any cutting. I'm very pleased with the product and support that Tuner Depot has provided.
So glad I went with TunerDepot! These guys have the best customer service and answered all my questions leading up to my purchase. Shipping was quick as I received my kit in 2-3 days. Everything to install was straight forward. I received an email with attached pdfs that included instructions on each item except for the EGR. I found a video by Dark Iron Diesel on Youtube, very helpful for the EGR if you have not done it before. Lastly, I installed a 13-18 5" SS exhaust I had laying around on my 19. Did not fit at all, but not difficult to shorten downpipe/reweld flange in order to fit stock downpipe on my 19. Also threw on a SS muffler from TunerDepot. Sounds great, but still pretty damn loud!
Outstanding Fuc’n stand customer service, had a missing part on Monday, when the mail came in,installed what I had on Tuesday and informed customer service about the missing part, then this morning on Wednesday the missing part arrived and finished the repair! I will be a frequent customer thank you tuner depot..!
I had a great experience with tuner depot. My tuner showed a error I so I contacted them and they sent me the file that I needed and I We'll use them on my next truck too. I give him five stars.
Ordered this for my truck to exchange my 4” one. Upon opening there aren’t really any instructions… though it seems straight forward it didn’t fit the first time we tried to put it on! It was way too long but it was the correct full exhaust so it took a second and what helped was putting the truck up on a lift to get completely under it. We did have to cut the turbo back hanger off as it didn’t fit and we had to unbolt the front dif to slide it under other than that perfect!
Had to cut about 12” off a segment to get it to fit. Once I did that, it fit together fine and the brackets fit perfect. Sounds good, but we will see about longevity.
My order arrived as described. I was short 1 clamp but my order was corrected after communicating to short item. The quality seems good. I did have to remove my transmission cross member to install the down pipe.
Fast shipping, everything came as described. Zero issues with shipping being damaged. Everything was installed and is it working properly. Very pleased
