DPF Delete Kits

What Is DPF Delete/Delete Pipe?

A DPF delete kit is an aftermarket upgrade kit used to remove the original factory DPF system from diesel vehicles.

The DPF (Diesel Particulate Filter) is designed to capture particulate matter in exhaust gases to meet emission standards. However, over time, the DPF can become clogged, requiring cleaning or replacement. This can even lead to the following problems:

• Excessive exhaust back pressure restricts engine intake;
• Frequent regeneration cycles waste fuel and time;
• Elevated exhaust gas temperature (EGT) increases the risk of engine damage;
• Reduced horsepower and fuel efficiency decrease.

That’s why many diesel owners choose a DPF delete kit — a solution to unleash your engine’s real potential.

Using SuncentAuto's DPF delete kit, you can replace the restrictive factory DPF with a free-flowing straight-through or racing-grade exhaust pipe, allowing exhaust gases to escape freely. This is typically used in conjunction with ECU tuning to disable the regenerative cycle and prevent fault codes, thereby unlocking the true potential of the diesel engine.

Pros and Cons of DPF Delete Kits

Key Advantages (Actual Measurement Data)

• Rugged and Durable: Made of T409 stainless steel, corrosion-resistant and high-temperature resistant.
• Horsepower Increase +20 hp: Depends on your engine and tuning settings.
• Torque Increase +25 lb-ft: Ideal for traction and acceleration.
• Fuel Economy Improvement 18%-23%: A smooth exhaust system leads to higher intake efficiency.
• Eliminating Maintenance Costs: No more DPF clogging issues after DPF removal; no cleaning or replacement required.
• Eliminating Regeneration Cycle: No more forced regeneration every 300-500 miles.
• Reduced Exhaust Temperature: Reduced by 100-300°F.
• Enhanced Throttle Response: Improved engine scavenging efficiency can improve throttle response by approximately 0.3 seconds.

Potential Disadvantages

• Legal Issues: In most areas, removing the emission control unit violates regulations. Generally limited to racetracks/off-road/private areas. (Please comply with local regulations.)
• ECU Tuning: The ECU must be tuned. Otherwise, fault codes may be triggered, power output may be reduced, or limp mode may be entered.
• Warranty Issues: This may affect the warranty. The original factory warranty/certificate may become invalid after modification.

In summary, while removing the DPF can significantly improve performance, it is only suitable for off-road use.

Vehicle Compatibility: Find Compatible Kits for Your Vehicle

Before choosing a DPF delete kit, the first step is to confirm your engine model, production year, and vehicle platform. SuncentAuto offers DPF removal kits for most mainstream diesel engines, including Powerstroke, Cummins, Duramax, and EcoDiesel.

How to Choose the Right DPF Delete Kit

After confirming compatibility, the next step is to select the appropriate exhaust pipe type based on your goals, budget, and performance requirements. Below are our exhaust pipe types and their corresponding features.

1. Straight Pipe

Maximizes exhaust flow and sound with virtually no resistance. Designed for users seeking racing-grade performance and a powerful exhaust note.

2. Race Pipe

Similar in structure to a straight-through pipe, but specifically designed for track environments, optimized for high-temperature durability and track conditions. Suitable for professional modification and racing applications.

3. DPF & CAT Delete

Simultaneously remove the diesel particulate filter and catalytic converter. This significantly reduces back pressure and releases maximum power. For off-road or racing use only.

4. Catalytic Converter & Muffler Delete Pipe

The catalytic converter and muffler are removed. While retaining some of the emission system, exhaust flow and sound performance are improved. Suitable for users who value sound quality.

5. Downpipe-Back DPF Delete

Replace the entire system from the downpipe to the tailpipe, and remove the DPF section. It offers a good balance between performance, cost, and ease of installation.

6. Turbo-Back DPF Delete

Replace the entire exhaust system, from the turbocharger outlet to the tailpipe. This can most noticeably improve power and sound, but it is also the most expensive and complex to install.
