---tab Description---
2016-2019 5.0 Cummins DPF Delete Downpipe-Back Exhaust Overview
Unleash the full potential of your 5.0L Cummins V8. The SPEtuner 4 inch to 5 inch Downpipe-Back Performance Exhaust is a premium, heavy-duty upgrade custom-engineered for the 2016–2019 Nissan Titan XD. This 5.0 Cummins DPF delete system is designed to remove the massive, restrictive factory DPF and SCR assembly, allowing your twin-turbocharged V8 engine to breathe, spool, and pull like never before.
The factory emissions equipment on the Titan XD is a major thermal bottleneck, trapping excessive heat and forcing your truck into frequent, power-robbing regeneration cycles. Our performance exhaust replaces this "cork" with a high-velocity 4-inch to 5-inch mandrel-bent system. By slashing backpressure to zero, you gain an immediate boost in turbo response, lower EGTs under load, and the deep, rich exhaust note that the Cummins V8 is famous for.

Key Features
- High-Flow 4" to 5" Expansion: Transitions smoothly from the turbo downpipe into a massive 5-inch straight-through exhaust body, eliminating the restrictive factory emissions filters.
- Drastically Lower EGTs: Essential for the Titan XD's compound-turbo setup; dumping exhaust heat instantly prevents thermal saturation and protects your pistons and head gaskets during heavy towing.
- Instant Turbo Spool & Response: Removing downstream restrictions allows your twin turbos to spool up instantly, eliminating the sluggish low-end response often felt in stock trucks.
- Eliminate Emissions-Related Downtime: Permanently bypass the DPF and SCR sensors that often trigger "Reduced Engine Power" mode, keeping your truck on the road and out of the dealership.
- Boosted Fuel Efficiency: Eliminating fuel-hungry DPF regeneration cycles saves raw diesel fuel and increases your overall towing MPG.
- Signature Cummins V8 Rumble: Unleashes that unmistakable, deep, and aggressive V8 diesel roar without the obnoxious, high-pitched "hiss" of the stock emissions system.
Package Include
Clamps, hangers and hardware are included. You may have to re-use some factory hardware.
The EGR Delete Kit, Hot Side Intercooler Piping Kit and UP-Pipe are included only when you select one of the corresponding combination options. These additional parts are not listed as included with the standalone 4 inch or 5 inch downpipe-back options.
Installation

Install takes about 1hr with basic hand tools, done on the ground of your driveway or garage. Quicker if you have an automotive-style lift. Cutting may be required to fit shorter wheelbase bed/cab configurations. Clamps, hangers, and hardware are included. You may have to re-use some factory hardware.
Tuner Required: Removal of the DPF, CAT, SCR, and/or DOC involves removing and eliminating emission-related sensors. A DPF delete capable tuner is required to prevent any check engine light or diagnostic trouble codes from setting.
What Is the DPF and Is It Worth Doing a DPF Delete?
Most post-2007 diesel vehicles are fitted with a Diesel Particulate Filter (DPF) for emissions reasons; however, there are a few disadvantages to this device, including constant maintenance and repairs.
Because the DPF clogs up, it increases backpressure. Due to this pressure, the fuel flow is hugely disturbed and slowed down. Therefore, when you remove this filter, the fuel flows much more easily and faster, increasing the overall fuel mileage.
Benefits: Expect to see a significant increase in fuel mileage. If your DPF is plugged up your probably averaging about 13-14 mpg. More or less depending on the severity of the restriction. After deleting the DPF/CAT expect to get a combined mileage of 18-19 mpg.
- It removes the need to service the DPF at regular intervals (cleaning, replacement)
- A DPF delete will remove the possibility of a DPF failure, which could cause expensive diesel repairs
- Due to less exhaust backpressure, the DPF delete increases exhaust flow and therefore increases the performance of your motor!
- Paired with an ECU remap, the DPF delete is proven to increase power and torque for all vehicles
Choose the Correct Nissan Titan DPF Delete Configuration
The standalone options are intended for buyers who need the 4-inch or 5-inch downpipe-back exhaust. The two combination options add the EGR Delete Kit, Hot Side Intercooler Piping Kit and UP-Pipe identified in their Shopify option names.
If you purchase a standalone exhaust and need the additional intake-side components separately, review the 2016–2019 Nissan Titan 5.0L Cummins EGR Delete Kit, Hot Side Intercooler Piping Kit and UP-Pipe. Do not order the separate kit if the same components are already included in your selected combination option.
A DPF delete addresses the factory emissions equipment, but it may not correct an unrelated engine, turbocharger, fuel-system or cooling-system problem. Review the 5.0 Cummins problems and repair-priority guide when diagnosing an existing Nissan Titan XD issue.
