SPEtuner DPF/EGR/DEF Delete Kit 2016-2019 Nissan Titan 5.0L Cummins All-in-One Kit

Maximize the performance, fuel efficiency, and long-term reliability of your 2016–2019 Nissan Titan XD 5.0L Cummins with the ultimate All-In-One Emissions Delete Suite. This comprehensive bundle combines a high-flow downpipe-back exhaust system, a complete EGR cooler delete kit, and an upgraded hot-side intercooler piping setup. By eliminating restrictive factory particulate filters, failure-prone EGR components, and burst-prone rubber intercooler boots, this system drastically reduces exhaust backpressure, lowers EGTs, and bulletproofs your truck for severe off-road and towing performance.

Key Features

• 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 & Airflow Velocity: Replaces restrictive downstream emissions equipment with a smooth, continuous high-flow path (available in 4" or 5" options) and boosts intake airflow by up to 80% with upgraded hot-side intercooler piping and up-pipes.
• Improved Twin-Turbo Response & Power: Removing factory bottlenecks lets your sequential turbochargers spin up instantly, curing low-end lag and unlocking an immediate gain of 25+ horsepower.
• Maximized Fuel Economy (MPG): By ending active DPF regeneration cycles and clearing intake restrictions, drivers typically see a real-world improvement of 3 to 5 MPG and combined highway mileage scaling up to 18–19 MPG.
• 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.

Specification

What's Included in the All-in-One Kit

---tab FAQ---

FAQ

Q1: Is custom tuning required to run this delete kit on the 5.0L Titan XD Cummins?
A1: Yes. The Nissan Titan XD 5.0L Cummins uses an ECM that strictly monitors DEF dosing, EGR position, and DPF differential pressure. Installing this physical kit without flashing a delete-capable custom ECM tune will instantly trigger Check Engine Lights, speed limiters, and a non-start countdown.

Q2: Does the EGR removal on the 5.0L Cummins V8 require removing the turbocharger?
A2: No, but engine bay space is extremely tight. The 5.0L Cummins V8 uses a sequential dual-stage turbocharger setup mounted in the engine valley. While turbo removal is not required, removing the secondary EGR cooler components on the firewall side requires patience, specific swivel sockets, and working through the wheel wells.

Q3: What should I do with the DEF tank and fluid lines after completing the delete?
A3: Once the delete tune is flashed to the ECM, the DEF pump and dosing injector are disabled electronically. You can unplug the wiring connectors, drain the DEF tank, and leave it mounted, or completely unbolt the DEF tank and fluid lines to free up undercarriage space and save weight.

Q4: How does deleting the emissions system affect the Aisin 6-speed automatic transmission?
A4: Deleting the DPF/EGR reduces turbo lag and improves throttle response on the 5.0L Cummins. To maintain smooth shifting and protect internal clutches under increased low-end torque, using a delete tune that optimizes TCM (Transmission Control Module) shift torque management is highly recommended.

Q5: Do I need to disconnect or unplug the factory EGT and NOx exhaust sensors?
A5: Yes. Once the factory DPF/SCR exhaust assembly is unbolted, unplug the wiring harness connectors for all EGT, NOx, and pressure differential sensors. Secure the vehicle-side plugs with electrical tape and zip ties out of harm's way; the delete tune disables these sensor feedback loops.

Q6: Will this kit fit both Single Cab and Crew Cab Titan XD models?
A6: Yes. The exhaust components include modular intermediate extension pipes to accommodate standard wheelbase lengths (Crew Cab/Short Bed and Single Cab/Long Bed). Minor trimming of the straight extension pipe with a saw may be necessary depending on your exact frame configuration.

Q7: Does removing the EGR cooler impact cold-weather engine operation?
A7: Removing the EGR cooler slightly extends engine warmup time in sub-zero winter conditions because hot exhaust gas is no longer recirculated into the intake. Allowing the engine a short idle warmup or using a front grille winter cover helps reach normal operating temperatures efficiently.

Q8: Can this installation be fully reversed if I need to return the truck to stock?
A8: Yes. The system uses bolt-on flanges and slip-joint clamps designed to attach to factory chassis rubber hangers. No permanent cutting or welding of the frame or engine components is required, allowing you to reinstall the factory OEM emissions equipment if needed.
