As a seasoned Dodge Ram Cummins installer, the 2013-2018 6.7L diesel models boast a solid factory build but suffer from carbon buildup, high exhaust backpressure and poor cooling in EGR, DPF and stock intake parts after long use—limiting power and raising maintenance costs. This guide shares a field-tested upgrade plan with TruckTok’s compatible parts, covering core power mods, protection and towing gear, all based on real installation and road tests for fellow owners.

1. EGR System Modification: Eliminate Clogging & Overheating​

The factory EGR recirculates high-temperature exhaust, causing intake carbon buildup, high coolant temp and extra engine load. TruckTok’s 2013-2018 EGR Valve Cooler Delete Kit (aluminum alloy + silicone) replaces stock parts directly with no extra accessories, cuts exhaust recirculation, lowers coolant temp, and has a pre-tapped plate for EGT probes, solving carbon buildup at the source.

For 2009-2024 compatibility, this EGR Delete Kit features a precision-sealed aluminum plate and integrated DDC bracket (direct engine mount, no exhaust stud removal). It diverts coolant to the cylinder head rear for better circulation—not for Cab & Chassis trucks.

Prioritize safety and intake efficiency with this 2007-2024 Universal EGR Throttle Delete Kit. TIG-welded, pressure-tested and corrosion-resistant, it removes the factory butterfly valve to reduce turbulence, sharpen throttle response and prevent high-speed throttle failure. It fits all 2013-2018 6.7L Cummins 2500/3500/4500/5500 models, even with partial EGR retention.

2. Intake System Upgrade: Unlock Turbo Potential​

The stock intake’s narrow pipe restricts air flow and turbo efficiency—even with EGR mods. TruckTok’s 3.5inch High Flow Intake Elbow is made of 16-gauge T304 stainless steel, mandrel-bent (wrinkle-free) and pre-grooved for the dipstick line (drill-free installation). Fully TIG-welded, it boosts intercooler efficiency by 50%, spools turbo faster and delivers instant power gains—ideal for EGR/DPF mods, fitting all 2013-2018 6.7L Cummins models.

3. DPF System Modification: Reduce Backpressure, Release Hidden Power​

The factory DPF is prone to clogging and frequent regeneration, cutting power and raising repair costs. TruckTok’s T409 stainless steel DPF delete exhausts (corrosion/durable) fit all usage scenarios:
  • Commercial Cab & Chassis: 4" DPF Delete Exhaust (2013-2019 3500/4500/5500) deletes DPF/CAT, boosts power/torque and optimizes fuel economy—no more DPF maintenance.
  • Daily/light off-road: 4" DPF Delete Pipe Kit (2013-2018 2500/3500) is cost-effective, includes full hardware, sharpens throttle response and eliminates DPF failures—easy DIY installation.
  • Off-road performance: 4" Muffler-Free DPF Delete Pipe delivers maximum flow, lower backpressure and aggressive sound—not for Cab & Chassis/air suspension models.
  • Ultimate performance: 5" Turbo-Back DPF Delete Exhaust replaces the full turbo-to-tailpipe system, delivers massive torque/horsepower gains and deep sound—fits leaf/coil spring models, not Cab & Chassis/air suspension.​

4. CCV Upgrade: Eliminate Turbo Oil Buildup​

Intake/DPF mods expose the stock CCV’s flaw: oil buildup on turbo/intercooler, reducing efficiency and lifespan. TruckTok’s 2007.5-2018 CCV Crankcase Vent Kit converts closed to open ventilation, with corrosion-resistant materials and 90° hoses for efficient oil drainage. It eliminates turbo oil contamination, keeps intercooler clean and protects intake/turbo systems—a must-have for high-flow/DPF mods, fitting 2013-2018 6.7L Cummins 2500/3500.

5. All-in-One Mod Kits: One-Stop EGR/DPF/CCV Delete​

Individual EGR+DPF+CCV parts risk compatibility issues—TruckTok’s all-in-one kits include the Mini Maxx Tuner V2 (disables EGR/DPF/DEF, optimizes performance, beginner-friendly, no separate tuning):
  • 4" All-in-One Delete Kit: 4" DPF/CAT delete exhaust, EGR/CCV parts + tuner. Boosts power/fuel economy, monitors EGT/boost, switches towing/street/racing modes—fits 2013-2018 2500/3500, not Cab & Chassis.
  • 5" All-in-One Delete Kit: 5" muffler-free turbo-back exhaust + EGR/CCV parts + tuner. Eliminates oil/carbon buildup, delivers extreme power gains—fits 2013-2018 2500/3500 leaf/coil spring models, not Cab & Chassis.

6. Tuning Accessory: EZ-Lynk/CCV SOTF On-the-Fly Switch​

For EZ-Lynk AutoAgent users, this 2010+ EZ-Lynk/CCV SOTF Switch is essential. Made of high-temperature wire, it features clean wiring and lets you switch tuning programs while driving (no stopping) for towing/highway/off-roading. Seamlessly compatible with 2013-2018 6.7L Cummins models.

7. Truck Bed Cover: Protection & Aesthetics, Drill-Free​

TruckTok’s soft roll-up/hard tri-fold bed covers (5.7FT/6.4FT/8FT) fit 2013-2018 Ram 2500/3500, drill-free, blending protection and style:
  • Soft Roll-Up (8FT/6.4FT/5.7FT): PVC material, wear/weather-resistant, lightweight, easy to operate—secures cargo from theft/weather, DIY install.
  • Hard Tri-Fold (8FT/6.4FT/5.7FT): Fiberglass construction, superior hardness/impact resistance, adjustable opening angles—clamp-on install, boosts truck texture, not for toolbox/Rambox models.

8. Towing & Rescue Gear: High-Strength for Modified Power​

Modified 6.7L Cummins needs heavy-duty towing/rescue gear—TruckTok’s 2" receiver parts fit stock bumpers, ideal for heavy towing and off-roading:
  • Daily Towing: Tri-Ball Hitch Mount (1-7/8"/2"/2-5/16" balls, 5000/6000/10000 lbs capacity) + 3/4" D-ring for light off-road—heavy-duty steel, black powder coat, fits Class III-V hitches.
  • Adjustable Towing: 6" Drop/Rise Adjustable Hitch (premium aluminum, rust-resistant) with 12000/7500 lbs capacity and double anti-theft locks—1" precision adjustment, universal fit.

Final Thoughts & Installation Tips​

These mods boost performance, reliability, and functionality—all parts are installer-tested. Key tips:
  • Always use a tuner with emissions deletes.
  • Take time installing—avoid rushed mistakes.
  • Measure bed length before ordering a cover.
  • Use a torque wrench for engine/exhaust parts.
  • All "Delete" performance parts are strictly for off-road or race use only. Check your local regulations, legal issues will be borne by oneself
