This All-in-One bundle provides the major tuning, exhaust, and emissions-removal components in one complete package.
Vehicle Compatibility
This RAM 6.7 Cummins C&C delete kit is designed for:
- Years: 2013, 2014, 2015, 2016, 2017, 2018
- Make: Dodge / Ram
- Models: 3500, 4500, 5500
- Engine: 6.7L Cummins Turbo Diesel
- Body style: Cab & Chassis only
- Transmission options: 68RFE or AISIN where applicable
- Factory systems: DPF, DEF/SCR, EGR
- Application: Off-road and competition use
Cab & Chassis exhaust routing differs from standard pickup models, so pickup exhaust parts should not be substituted. EFI Live tuning in this configuration is also not intended for trucks that require PTO operation.
How work?
The 2013, 2014, 2015, 2016, 2017, 2018 6.7 Cummins Cab & Chassis delete kit combines physical emissions removal with a fixed EFI Live engine calibration. The exhaust pipe removes restrictive factory aftertreatment components, while the EGR kit removes the valve, cooler, and soot recirculation path. EFI Live then recalibrates the engine for the modified hardware, stopping supported DPF regeneration, DEF/SCR monitoring, and related derate functions. Reduced exhaust restriction can improve throttle response, boost response, and power delivery under sustained work loads.
Features
Unlike pickup tuning packages that may use multiple SOTF settings, this delete kit for 6.7 Cummins Cab & Chassis 2013-2018 uses a fixed commercial-truck calibration. Owners select either factory-like Stock Optimized power or a +60 HP tune.
The hardware is designed around Cab & Chassis frame and exhaust geometry. A 4-inch Delete Pipe is available for retaining more of the rear exhaust, while a complete 5-inch system provides a larger-diameter upgrade.
The package removes EGR-related soot buildup but does not replace normal CCV, cooling-system, fuel-system, or engine maintenance.
Tuning & Settings
The 6.7 Cummins Cab & Chassis delete kit uses two fixed engine settings:
| Tune | Power Increase | Intended Use |
| Stock Optimized | 0 HP | Factory-like work-truck power and predictable response |
| Performance | +60 HP | Added horsepower for towing, hauling, and off-road performance |
This Cab & Chassis configuration does not use five-level SOTF tuning.
| Characteristic | Expected Result |
| Power | 0 or +60 HP |
| Throttle Response | Improved with the matching tune |
| Exhaust Backpressure | Reduced after DPF/SCR restriction removal |
| EGTs | May run lower under comparable load |
| Fuel Economy | Potential improvement depending on route, payload, gearing, and driving style |
| Towing / Hauling | More consistent power delivery; factory GVWR, GCWR, axle, and payload ratings remain unchanged |
| Reliability | Removes several DPF, DEF/SCR, and EGR-related failure points |
Optional Add-Ons
- No TCM Tune – retains the existing factory transmission calibration.
- 68RFE TCM Tune – transmission calibration for supported trucks equipped with the 68RFE.
- AISIN TCM Tune – transmission calibration for supported AISIN-equipped models.
- 4-Inch DPF Delete Pipe – retains a compatible rear exhaust while removing the factory aftertreatment section.
- 5-Inch Exhaust System – larger stainless exhaust system for increased flow and deeper sound.
- No Muffler – straight-pipe configuration with maximum exhaust volume.
- With Muffler – reduces sound level and cabin drone.
Key Benefits
Cab & Chassis-Specific Fitment – exhaust components are designed around commercial 3500, 4500, and 5500 chassis routing.
Fixed Commercial Calibration – Stock Optimized and +60 HP tunes provide straightforward power choices without unnecessary multi-level switching.
Reduced Exhaust Restriction – removal of the factory aftertreatment system improves exhaust flow.
Cleaner Intake Path – EGR valve and cooler removal reduces soot recirculation and buildup.
Transmission Options – the 2013-2018 6.7 Cummins C&C delete kit can be configured for supported 68RFE or AISIN applications instead of using one generic transmission setup.
Installation Information
Installation instructions are supplied with the package. The job requires solid mechanical skills because the full process includes exhaust removal, EGR cooler removal, coolant rerouting, block-off hardware installation, and engine programming.
Typical tools include metric sockets and wrenches, extensions, a torque wrench, penetrating oil, hose-clamp pliers, line tools, a drain pan, safe lifting equipment, a battery charger or support unit, and a Windows laptop for EFI Live.
Plan approximately 5-8 hours for the complete installation. High-mileage trucks with seized clamps, corroded fasteners, body equipment, or difficult EGR connections may require additional shop time. EFI Live programming is completed separately through AutoCal V3 after the correct custom file has been prepared and loaded.
No More Emissions Codes
Correct EFI Live programming prevents supported warnings, regeneration requests, limp mode, and derate conditions caused by the removed factory emissions components. Normal diagnostics for unrelated engine, fuel, turbo, transmission, wiring, and sensor faults remain active.
Common applicable code families include:
- DPF: P2002, P242F, P2452, P2453, P2458, P2459, P2463, P246C
- EGR: P0401, P0402, P0404, P0405, P0406
- DEF/SCR: P203B, P204F, P205B, P207F, P208A, P20B9, P20BA, P20EE, P229F, P249D
Exact DTC coverage depends on the ECM strategy and installed tune.
FAQ
The package is built specifically around commercial-frame models rather than adapting pickup parts. It combines EFI Live tuning, EGR removal, DEF/SCR and DPF calibration, Cab & Chassis exhaust hardware, and selectable transmission options in one package.
EFI Live AutoCal V3 loads vehicle-specific custom calibration through the factory OBD connection and supports data logging for tuning support. The C&C application uses fixed Stock Optimized or +60 HP files rather than pickup-style SOTF tuning.
The Performance calibration adds +60 HP. The package also removes several emissions-system components that can cause regeneration, derate, cooler, valve, and aftertreatment problems, although normal mechanical maintenance remains essential.
The 2013, 2014, 2015, 2016, 2017, 2018 platform may see improved fuel efficiency after reducing exhaust restriction and eliminating normal regeneration. Actual results depend heavily on payload, idle time, axle ratio, route, tires, and driving conditions.
The +60 HP tune can provide stronger and more consistent power delivery while hauling or towing. The upgrade does not increase factory GVWR, GCWR, axle, hitch, or payload limits.
A skilled owner can install the full package with appropriate shop equipment and EFI Live software experience. Because this commercial-truck setup involves EGR coolant work, Cab & Chassis exhaust routing, transmission selection, and custom programming, professional installation is a practical option for less experienced owners.

Customer service helped me choose the correct kit and made ordering simple. Shipping was faster than expected and instructions were emailed in advance. The truck now runs stronger, sounds great, and is no longer in limp mode. Overall performance improvement is significant.
Spent about four hours installing it with my son. Only needed to trim a small section of pipe. EGR will be removed later, but the truck already feels and sounds far better.
Tuning was very simple, the EGR delete kit included everything needed, and the exhaust fit perfectly without modification. All hangers aligned correctly. Extremely satisfied and would buy another kit from this source.
Anyone with common sense and a wrench will love this setup. If that’s not you, maybe sit this one out.
Everything installed smoothly except the tailpipe, which required some trimming and welding. Still very satisfied with the outcome.
