2017-2025 6.6L Duramax EGR delete kit instruction
Tuner Required for Installation: Installing a 6.6 Duramax delete pipe requires more than just swapping out hardware. When removing 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.
How to Choose DPF Delete Kit?
4ā vs 5ā Straight Pipe Comparison
When choosing a 6.6 Duramax delete pipe, the most common options are 4-inch and 5-inch straight pipes.
The 4-inch straight pipe delivers a tighter, raspier exhaust noteāespecially noticeable at lower RPMsāmaking it ideal for daily driving or mildly tuned setups where excessive drone is undesirable.
In contrast, the 5 inch straight pipe 6.7 DuramaxĀ offers a deeper, more refined tone with less high-pitch resonance. It excels in high-output builds and towing scenarios, where increased exhaust flow is beneficial.
Driver feedback suggests:
-
4āstraight pipe is great for stock-to-lightly-modded trucks and a quieter cabin
-
5āstraight pipe is perfect for aggressive builds, deeper tone lovers, or anyone maximizing exhaust performance
Different Types of DPF Delete

DPF Race Delete
- Only removes the DPF (keeps stock downpipe)
- Minimal performance gain but cheapest option
- Best for budget-focused or emissions-testing avoidance
Downpipe-Back Delete
- Replaces exhaust from the turbo downpipe backward
- Improves mid-range power and throttle response
- Good for street builds keeping stock turbo
Turbo Back Delete
- Full system replacement from turbo outlet
- Includes high-flow downpipe for maximum efficiency
- Reduces turbo lag and boosts top-end power
- Top choice for tuned/high-performance engines

---tab FAQ---
Q1. Will I need a tuner after installation?
A1. Yes!Ā Deleting the EGR and DPF requires aĀ custom tuneĀ to prevent check engine lights and ensure proper engine operation. The factory ECU expects these systems to function, so a tuner (like SCT, H&S, or EZ Lynk) is necessary to optimize performance.
Q2. Does this kit improve fuel mileage?
A2. Many users reportĀ 1-3 MPG gainsĀ after deleting the DPF, as the engine no longer wastes fuel on forced regenerations. Combined with a proper tune, you can maximize efficiency.
Q3. How difficult is the installation?
A3. Installation isĀ moderate to advancedĀ and requires mechanical experience. The DPF delete involves exhaust modifications, while the EGR delete requires removing the cooler and related components. Some welding may be needed depending on the kit configuration.
Q4. Will deleting the EGR/DPF hurt my engine?
A4. Noāin fact, itĀ reduces engine stressĀ by eliminating soot buildup in the intake (from EGR) and excessive backpressure (from the DPF). However, proper tuning is critical to avoid issues.
Q5. Does this kit include everything I need?
A5. Most kits includeĀ EGR block-off plates, DPF delete pipes, clamps, and hardware, but some may require additional components (like a tuner or up-pipes). Always check the product description before purchasing.
Q6. Can I pass emissions testing after installing this kit?
A6. No. Since the EGR and DPF are removed, your truck willĀ not pass emissions inspectionsĀ in states that require them. You may need to reinstall stock components for testing.
Q7. Will my truck throw check engine lights (CELs) after install?
A7. Without a proper tune,Ā yesāthe ECU will detect missing emissions components. A quality tuner will disable these codes and optimize performance.
Q8. How much horsepower can I gain?
A8. Results vary, but many users seeĀ 50-100+ HP gainsĀ (with tuning) due to reduced exhaust restrictions and improved airflow.
