DPF/DEF/EGR Delete Kit with EZ LYNK AUTOAGENT 3 for 2019-2021 6.7L Cummins 2500 3500 All-in-One Kit

SPEtuner EZ LYNK/DPF/EGR Delete All-in-One Kit | 2019-2021 Dodge Ram 6.7L Cummins

Unlock the ultimate performance, reliability, and fuel efficiency of your 2019–2021 RAM 2500/3500 6.7L Cummins with the SPELAB EZ LYNK & All-In-One Emissions Delete Suite. This complete performance bundle pairs an industry-leading EZ LYNK AutoAgent tuning device with a high-flow DPF/DEF delete race pipe and a heavy-duty EGR delete kit. By eliminating restrictive factory aftertreatment equipment and soot-clogged emissions components while calibrating your ECM for flawless operation, this package drastically reduces backpressure, lowers EGTs, and bulletproofs your truck for severe heavy-duty towing and off-road use.

Key Features

• EZ LYNK Cloud-Based Tuning: Quickly flash your truck, track real-time data, and manage your tunes with the easy-to-use EZ LYNK platform, giving you full control over your vehicle's performance.
  
• Total Emissions Assembly Eradication: Permanently bypass the restrictive DPF, DEF/SCR, and EGR systems, eliminating the need for fuel-thirsty, power-robbing active regeneration cycles that cause long-term thermal fatigue.
• Massive High-Flow Exhaust Velocity: Replaces restrictive downstream emissions equipment with a smooth, continuous high-flow path (available in 4" or 5" options), drastically reducing exhaust backpressure and protecting your precision turbocharger from thermal strain.
• Drastically Drops EGTs (Exhaust Gas Temps): Eliminating the thermal cork of the factory exhaust and recycling of hot exhaust gases allows hot air to evacuate instantly, safeguarding your engine internals and head gaskets during heavy towing.
• Improved Turbo Response & Power: Removing factory bottlenecks lets your Variable Geometry Turbocharger (VGT) spin up with significantly less effort, curing lag and providing immediate, smooth power delivery across the RPM range.
• Engine Longevity & Clean Airflow: Keeping abrasive soot and carbon out of your intake valves and cylinders ensures your engine oil stays cleaner and your motor runs reliably for hundreds of thousands of miles.

FAQ

Q：How do I choose the right DPF Delete Pipe?

A：Choose based on your sound preference and performance requirements. 4" systems are suitable for daily driving with a balanced tone, while 5" systems offer better airflow and a more aggressive exhaust sound. Muffler versions reduce drone, while race versions are louder and more aggressive.

Q：What is the difference between Single Tune and SOTF Tune?

A：Single Tune offers one fixed performance calibration, while SOTF (Switch-On-The-Fly) allows you to switch between different performance levels on the go, offering greater flexibility.

Q：How long does shipping take for the EZ Lynk tuner?

A：The tuner generally ships within 5–10 business days and may be shipped separately from other items.

Q：Is this kit street legal?

A：No. This product is designed for off-road, race, or competition use only, where emissions equipment removal is legal. Be sure to check local regulations before purchasing.

Q：Is professional installation recommended?

A：Yes. Professional installation is strongly advised to ensure correct fitment, proper tuning, and safe operation.
