Description

What’s Included

Component Description
EZ Lynk Auto Agent 3 Cloud-based tuner that connects through the OBD-II port and works with the AutoAgent mobile app for VIN-specific tune delivery, live monitoring, diagnostics, and remote support.
Custom Engine Tuning Calibration is matched to the truck’s year, ECM, engine, and Cab & Chassis configuration. Available power depends on the model year.
DPF/CAT Delete Pipe Cab & Chassis-specific stainless exhaust pipe replaces the restrictive factory particulate-filter and aftertreatment section while maintaining the correct commercial-frame routing.
EGR Delete Kit Includes block-off components and supporting parts required for removal of the factory EGR valve and cooler from the recirculation system.
Installation Hardware Includes the clamps, fittings, fasteners, and connections required for the supplied exhaust and EGR components.

This All-in-One bundle provides the major parts and tuning needed for a complete DPF, DEF/SCR, and EGR off road solution.

Vehicle Compatibility

This RAM 6.7 Cummins Cab & Chassis delete kit is designed for:

  • Years: 2019, 2020, 2021
  • Make: Dodge / Ram
  • Models: Ram 3500, Ram 4500, Ram 5500
  • Engine: 6.7L Cummins Turbo Diesel
  • Body style: Cab & Chassis
  • Factory systems: DPF, DEF/SCR, EGR
  • Application: Off road and competition use

The commercial chassis uses different exhaust routing from a standard pickup, so this package should not be replaced with 2500 or 3500 pickup parts. The correct truck information should be used when the tune is prepared.

How work?

The 2019, 2020, 2021 6.7 Cummins Cab & Chassis delete kit combines physical emissions removal with matching ECM tuning. The exhaust pipe removes the restrictive DPF/CAT and SCR aftertreatment section, while EGR valve and cooler removal stops exhaust gas and soot from being recirculated through the intake. EZ Lynk programming changes the supported emissions strategies to match the installed hardware and eliminates normal regeneration operation. Reduced restriction can improve exhaust flow, throttle response, boost response, and usable engine performance.

Features

The delete kit for 6.7 Cummins C&C 2019-2021 is built specifically around commercial-frame trucks rather than adapting a pickup solution. Cab & Chassis models receive year-specific single-tune calibration instead of assuming one universal power ladder.

EZ Lynk Auto Agent 3 gives the owner smartphone-based access to tuning, diagnostics, and live diesel data without requiring a dedicated display. The 2018+ Ram ECM architecture also uses the appropriate bypass/patch connection during programming.

The package focuses on emissions-system components; normal CCV, fuel-system, cooling-system, and engine maintenance remain part of regular truck service.

Tuning & Settings

The 2019-2021 6.7 Cummins C&C delete kit uses single-tune files, with available horsepower depending on model year:

Model Year Available Engine Tunes
2019 0 HP, +50 HP, +75 HP, +100 HP
2020 0 HP, +50 HP, +75 HP, +100 HP
2021 0 HP, +50 HP, +100 HP

These commercial-truck calibrations are selected as fixed tunes rather than five-position SOTF power levels.

Characteristic Expected Result
Maximum Power Increase Up to +100 HP
DPF Regeneration Eliminated after correct hardware removal and tuning
Exhaust Restriction Reduced with the factory filter and aftertreatment section removed
Throttle Response Improved through matching calibration and freer exhaust flow
Fuel Economy Can improve depending on payload, idle time, gearing, route, and tune
Towing / Hauling Additional torque and power can improve response under load; factory weight ratings do not change
Emissions-System Reliability Removes several DPF, DEF/SCR, and EGR-related failure points

Optional Add-Ons

  • No Muffler – straight-pipe configuration for a louder exhaust note and maximum sound.
  • With Muffler – reduces exhaust volume and cabin drone while retaining the freer-flowing delete-pipe layout.

Both choices use the Cab & Chassis-specific exhaust route rather than a standard pickup system.

Key Benefits

Up to +100 HP – year-specific tune selection provides additional power without treating every 2019-2021 ECM calibration as identical.

Commercial-Truck Fitment – exhaust hardware is built specifically for 3500, 4500, and 5500 Cab & Chassis models.

Cloud-Based Tuning – EZ Lynk provides mobile access to tune files, monitoring, diagnostics, and technical support.

Reduced Soot Buildup – EGR removal helps keep recirculated soot out of the intake path.

Complete Matched Package – the tuner, pipe, EGR components, block-off hardware, and supporting parts are combined so owners do not have to shop for everything separately.

Installation Information

Installation instructions are supplied with the kit. An experienced owner can install the hardware, although the full job requires more skill than a simple exhaust replacement because it includes EGR cooler work, coolant handling, sensor connections, and ECM programming.

Recommended tools include metric sockets and wrenches, extensions, a torque wrench, penetrating oil, hose-clamp pliers, a drain pan, exhaust tools, safe lifting equipment, a smartphone, reliable internet access, and battery support during tuning.

Plan approximately 5-8 hours for a complete installation depending on corrosion, installed body equipment, access around the cooler, and previous upgrades. EZ Lynk setup and tune flashing are completed through the AutoAgent app using the correct VIN-specific profile.

No More Emissions Codes

Correct EZ Lynk tuning prevents supported warning lights, regeneration requests, limp mode, and derate conditions caused by the removed emissions systems. Normal diagnostics remain active for unrelated engine, turbo, fuel, transmission, wiring, and sensor faults.

Common applicable code families include:

  • DPF: P2002, P242F, P2452, P2453, P2458, P2459, P2463, P246C
  • EGR: P0401, P0402, P0403, 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 specifically designed around late-model commercial Ram trucks, including their unique exhaust routing and ECM requirements. It combines compatible tuning, a Cab & Chassis pipe, EGR removal hardware, and supporting components instead of using a generic pickup kit.

EZ Lynk combines VIN-specific cloud tuning, mobile diagnostics, live monitoring, and remote file delivery in one compact interface. For this application, its main advantage is the ability to match the tune specifically to the year and C&C configuration.

Yes. Depending on model year, available single tunes provide up to +100 HP. The additional power and torque can improve acceleration and response under load without changing the truck’s factory tow or payload ratings.

The system can improve exhaust flow, throttle response, boost response, and operating efficiency while eliminating normal DPF regeneration. Fuel economy may also improve in comparable conditions, particularly when the truck spends less time in regeneration cycles.

Yes, if you are comfortable with diesel exhaust work, EGR removal, coolant routing, electrical connections, and ECM flashing. Owners without that experience should use a qualified shop because the late-model Cab & Chassis installation involves more than simply replacing an exhaust pipe.
