Top Upgrade Categories for the 2019–2024 Ram 6.7L Cummins
Tuners & Programmers — SGM-Compatible
This is where every 5th Gen build starts — and where most builds go wrong if you choose the wrong tuner.
Ram introduced the Security Gateway Module (SGM) starting with the 2019 model year. This module sits between the OBD-II port and the ECU, actively blocking standard tuning tools from communicating with the engine computer. The result: most older tuners that worked flawlessly on 4th Gen trucks are completely incompatible with 2019+ Ram HD vehicles without an SGM bypass.
The tuners we carry for the 2019–2024 6.7L Cummins are fully vetted for SGM compatibility:
- EZ LYNK AutoAgent 3.0 — The industry's leading cloud-based tuning platform for 5th Gen. Requires SGM bypass cable. Full remote tune support.
- H&S Mini Maxx V2 — Updated firmware with SGM bypass support for select model years.
- EFILive AutoCal V3 — Professional-grade solution for custom tuners; full data logging and calibration capability.
- Spade Tuner — Plug-and-play with built-in SGM bypass for qualifying 2019–2021 applications.
Note: Always verify tuner-to-model-year compatibility before purchasing. SGM bypass requirements differ between 2019–2021 and 2022–2024 model years.
Best for: All 5th Gen builds — a tuner is not optional, it's the foundation.
EGR Delete Kits
The 5th Gen 6.7L Cummins carries forward the same fundamental EGR problem as its predecessor — but with updated plumbing. The factory Exhaust Gas Recirculation system routes hot, oxygen-depleted exhaust back into your intake, progressively coating the EGR cooler, throttle body, and intake manifold with carbon deposits. On these trucks, EGR cooler failure is one of the most common and costly repairs in the 100,000–150,000 mile range.
Our 2019–2024 6.7 Cummins EGR delete kits replace the factory EGR cooler and valve with block-off plates and clean coolant reroute lines — stopping carbon contamination at the source. Available in:
- Throttle valve delete only
- EGR cooler + valve full delete
- EGR delete as part of a complete all-in-one bundle
Best for: Trucks approaching or past 80K miles, any build running a performance tune, and rigs seeing heavy towing cycles.
DPF & DEF Delete Pipes
The 5th Gen emissions stack — DPF (Diesel Particulate Filter), DOC (Diesel Oxidation Catalyst), and SCR (Selective Catalytic Reduction / DEF system) — represents the most restrictive factory exhaust architecture Cummins has ever had to work within. Active DPF regeneration cycles burn off accumulated soot under load, spiking exhaust temps and momentarily pulling power. The DEF/SCR system adds ongoing fluid cost, sensor complexity, and additional failure points.
Our 2019–2024 6.7 Cummins DPF delete race pipes (available in 4" and 5" diameter) replace the entire DPF/DOC/SCR section with a straight or high-flow muffled pipe — eliminating regen cycles, reducing exhaust backpressure, and freeing up significant power across the RPM range.
Available configurations:
-
4" downpipe-back delete pipe (street-profile fitment, quieter)
-
5" turbo-back system (maximum flow for high-HP builds)
-
Cab & Chassis / flatbed-specific fitments available
Best for: Off-road and competition builds, trucks no longer subject to emissions testing, or high-mileage rigs with failing DPF/SCR components.
CCV Reroute / Delete Kits
The Crankcase Ventilation (CCV) system routes oil blow-by vapors from the crankcase back through the air intake — and on the 5th Gen 6.7L Cummins, this causes the same issue it always has: oily residue coating your intercooler, intake piping, and turbo compressor wheel over time. The problem compounds after an EGR delete, since the intake tract now sees even more boost cycles without the oil-laden EGR gases to mask the buildup.
A CCV reroute kit redirects these vapors away from the intake with a catch can or open vent — keeping your charge air system clean and your turbo running efficiently for the long term.
Best for: Any build running an EGR delete, high-boost tunes, or trucks with 80K+ miles showing intercooler oil contamination.
All-in-One Delete Bundles
The most efficient way to build a clean, functional 5th Gen Ram is with a complete delete bundle — a matched kit containing the EGR delete, DPF race pipe, CCV reroute, and an SGM-compatible tuner, all confirmed to work together and fit your specific truck configuration.
Our all-in-one kits are sorted by:
- Cab style — Standard Cab, Crew Cab, Mega Cab
- Chassis type — Pickup vs. Cab & Chassis / flatbed (different exhaust routing)
- Transmission — 68RFE, Aisin AS69RC (6-speed auto), G56 manual
- Year range — 2019–2021 vs. 2022–2024 (SGM and ECU calibration differences)
Best for: Builders who want to do it once and do it right.
Exhaust Systems & Pipes
After deleting the DPF, the factory exhaust from the downpipe back becomes the flow restriction. We carry a full range of 5th Gen 6.7 Cummins exhaust systems from turbo-back to cat-back configurations:
- 5" turbo-back systems — Maximum exhaust flow for high-HP builds and heavy towers
- 4" downpipe-back kits — Quieter, street-friendly profile with meaningful flow gains
- High-flow performance mufflers — For builds that want tone without straight-pipe volume
- Stainless exhaust tips — 4"→5" and 5"→6" outlet, T304 stainless, 12" length
Sound note: 5th Gen trucks with a 5" turbo-back are noticeably louder than stock. If daily driver use is the priority, a 4" system with a quality muffler strikes the better balance.
Turbo & Intake Upgrades
The factory variable geometry turbocharger on the 2019–2024 6.7L Cummins is a refined unit — but it reaches its limits as fueling and boost demands increase with tuning. We carry supporting upgrades for builds pushing beyond stock power levels:
- Variable geometry turbo upgrades and drop-in replacements
- Cold air intake systems for increased airflow and improved inlet temps
- Charge pipe and intercooler upgrades for boost-fed applications
- EGT (Exhaust Gas Temperature) sensor relocation kits
- Boost and fueling support components

Critical 5th Gen Architecture Notes
- Security Gateway Module (SGM): Introduced in 2019, blocks standard OBD-II tuner communication. Requires SGM bypass cable or SGM-integrated tuner for any ECU calibration work.
- Compacted Graphite Iron (CGI) block: More rigid than standard gray iron — built for the increased cylinder pressure of the HO engine, but requires correct oil spec maintenance.
- Hydraulic lifters: 5th Gen design change from previous mechanical lifters — oil viscosity and change intervals matter more on this generation.
- Transmission options: 68RFE 6-speed automatic (standard output), Aisin AS69RC 6-speed automatic (High Output 3500), G56 6-speed manual (select configurations).
Recommended Maintenance Specs (5th Gen)
- Engine oil: CK-4 rated synthetic, CES 20086 standard — 10W-30 standard, 5W-40 in extreme temperatures.
- Oil change interval: Every 5,000–7,500 miles (do not exceed 10,000 miles).
- Fuel filter: Every 15,000 miles or as indicated.
- These intervals become more critical on tuned engines running elevated cylinder pressures.
FAQs
What is the Security Gateway Module (SGM) and why does it matter for tuning?
The SGM is a Stellantis/Ram security module introduced on 2019+ Ram HD trucks. It sits between the OBD-II diagnostic port and the vehicle's ECU, actively blocking unauthorized tune uploads and ECU communication. Standard tuners that worked on 4th Gen (2013–2018) trucks will not communicate properly with a 5th Gen truck without either a dedicated SGM bypass cable or a tuner with built-in SGM bypass capability. Always confirm SGM compatibility before purchasing a tuner for a 2019+ Ram.
Do I need a tuner to run an EGR or DPF delete on a 2019+ Ram?
Yes, without exception. Removing the EGR or DPF without recalibrating the ECU will trigger multiple fault codes, force the truck into limp mode, and can cause unsafe fueling conditions. A proper tune disables the relevant fault monitors, optimizes fueling and timing for the new configuration, and ensures the engine runs correctly. The SGM adds an additional layer to this requirement — your tuner must be able to communicate with the 5th Gen ECU.
What's the difference between 2019–2021 and 2022–2024 delete kit fitment?
While the core 6.7L Cummins engine is shared across the full 5th Gen run, there are differences in exhaust system geometry, sensor positioning, and ECU calibration between earlier and later model years. Some delete pipes and tune files are split between 2019–2021 and 2022–2024 builds. Always confirm the exact model year when ordering — we list fitment clearly for every product.
Will these parts fit my Ram 3500 Cab & Chassis / flatbed truck?
Cab & Chassis configurations have a different exhaust routing than standard pickup bodies — the DPF delete pipe and exhaust system fitment is not interchangeable. We stock Cab & Chassis-specific exhaust and delete solutions. Filter by your configuration when shopping, and contact us if you need fitment confirmation.
How much power can I realistically expect from a 5th Gen delete + tune?
A quality EGR/DPF delete paired with a stage 1–2 performance tune on a 2019–2024 6.7L Cummins typically yields 60–120 HP and 150–200 lb-ft of torque over stock, depending on starting configuration (standard vs. High Output) and tune aggressiveness. Fuel economy gains of 2–4 MPG in combined driving are commonly reported. Stage 3 and custom tunes can push further but generally require transmission upgrades.
Is the 68RFE transmission strong enough to handle a performance tune?
At Stage 1 power levels, a stock 68RFE typically holds up under normal use. However, the 68RFE is broadly considered the weak link in hard-use builds — especially with aggressive towing cycles or Stage 2+ tunes. If you're planning to push above 500 HP, tow regularly at high weight, or run an aggressive tune, a 68RFE valve body kit, upgraded clutch pack, or full billet rebuild is strongly recommended. The Aisin AS69RC (found in High Output 3500 models) is a more robust platform for high-power builds.
Are these products street legal?
EGR delete kits, DPF delete pipes, and DEF/SCR removal components are sold for off-road and closed-course competition use only. They are not legal for use on public roads or vehicles subject to emissions inspection in most U.S. states and Canada. Customers are responsible for understanding and complying with local emissions laws.
