Unlock the full potential of your diesel truck.
Whether you drive a Ford Powerstroke, Ram Cummins, or GMC Duramax, JS Speed Shop offers premium DPF, DEF, and EGR delete kits to boost power, improve fuel economy, and cut out costly repairs.

From full delete packages to precision-fit delete pipes, we carry trusted solutions for:
Why Delete Your DPF, DEF & EGR Systems?
Modern emissions systems like the Diesel Particulate Filter (DPF), Exhaust Gas Recirculation (EGR), and Diesel Exhaust Fluid (DEF) are known to clog, break down, and restrict your truck’s performance. For diesel owners running a Powerstroke, Cummins, or Duramax, these issues can lead to frustrating engine codes, limp mode, and expensive repairs.
A diesel delete kit eliminates these weak points — unlocking more horsepower, better fuel economy, and fewer breakdowns. Whether you're looking for a DPF delete kit, DEF delete tuner, or a full EGR delete system, we’ve got complete solutions to match your truck and tuning goals.
In this guide, we’ll explain what each system does, how deleting them improves performance, and why so many diesel truck owners trust delete kits and tuning to get the most out of their ride — on or off the road.
Why Delete Your DPF, DEF & EGR Systems?
Modern emissions systems like the Diesel Particulate Filter (DPF), Exhaust Gas Recirculation (EGR), and Diesel Exhaust Fluid (DEF) are known for clogging, breaking down, and restricting performance.
Our delete kits are designed for off-road and competition use to:
- Add 50–100+ HP with proper tuning
- Increase fuel efficiency by up to 5 MPG
- Stop costly issues like DPF regen, DEF limp mode, and EGR clogging
Diesel Particulate Filter (DPF)
The DPF traps soot and unburnt fuel particles from the exhaust to reduce emissions. Over time, the filter clogs and requires a regeneration process to burn off buildup. If the regeneration fails, the DPF may require replacement, which can be costly.
Issues with DPF systems:
- Increased exhaust backpressure, reducing power
- Expensive DPF replacements if clogged
- Reduced fuel efficiency due to regeneration cycles
Exhaust Gas Recirculation (EGR) Valve
The EGR system recirculates exhaust gases back into the engine to reduce nitrogen oxide emissions. However, it leads to carbon buildup, which can clog intake valves and reduce overall efficiency.
Drawbacks of EGR systems:
- Carbon buildup restricts airflow
- Increased risk of engine overheating
- Leads to costly repairs and maintenance
Diesel Exhaust Fluid (DEF) System
The DEF system injects a urea-based fluid into the exhaust to lower nitrogen oxide emissions. While effective for emissions control, it adds extra maintenance and potential breakdown risks.
Common DEF problems:
- Limp mode activation when the system fails
- Costly DEF refills and repairs
- Additional sensor failures
What Is a Diesel Delete Kit?
A diesel delete kit removes or disables DPF, DEF, and EGR systems, allowing your truck’s engine to operate more efficiently. A complete delete typically includes:
- DPF Delete – Removes the Diesel Particulate Filter and replaces it with a free-flowing exhaust pipe
- DEF Delete – Disables the DEF system, eliminating the need for fluid refills
- EGR Delete – Blocks off the EGR system to prevent carbon buildup
A delete kit usually requires an aftermarket tuner to adjust the truck’s computer settings for optimal performance after removing emissions components.
Advantages of DPF, DEF, and EGR Delete Kits
Removing these emissions systems can significantly improve your truck’s performance, efficiency, and longevity.
1. Increased Horsepower and Torque
Removing emissions restrictions allows for better airflow, improving engine performance and increasing horsepower by 50-100+ HP with proper tuning.
2. Improved Fuel Efficiency
Eliminating DPF regeneration cycles and the DEF system can increase fuel efficiency by 2-5 MPG, reducing long-term fuel costs.
3. Lower Maintenance Costs
Factory emissions systems often require expensive repairs or replacements. A delete kit eliminates the need for:
- DPF replacements (which can cost thousands)
- DEF fluid refills and sensor repairs
- EGR cleaning and replacement
4. Cooler Engine Temperatures
Removing the EGR system prevents excessive carbon buildup and reduces engine heat, lowering the risk of overheating.
5. Extended Engine Longevity
Without EGR carbon deposits, DPF clogging, and DEF system failures, your diesel engine can operate cleaner and last longer.
Should You Consider a Diesel Delete Kit?
While a diesel delete kit offers better performance and lower maintenance costs, it is important to consider:
- Legal restrictions – Deleting emissions systems is illegal for on-road use in many areas. Ensure compliance with local laws.
- Warranty concerns – Removing emissions components may void your truck’s manufacturer warranty.
If you use your truck for off-road, competition, or agricultural purposes, a delete kit can be a great investment for performance gains.
