What is Diesel Delete Kit?
A diesel delete kit is aftermarket parts for diesel trucks that remove emissions systems like EGR, DPF, and DEF to boost power, efficiency, and throttle response.
Key Benefits of Installing a Diesel Delete Kit
- Reliability: Stop sensor failures and limp mode for a truly dependable rig.
- Fuel Economy: Lower backpressure to boost MPG and save money at every pump.
- Performance: Gain significant horsepower and torque with sharper throttle response.
- Lower Costs: End expensive DEF refills and specialized DPF filter cleanings.
- Engine Life: Prevent soot buildup to protect core components for the long haul.
Diesel Delete Kits: Deleted vs. Stock
| Feature |
Deleted (with Diesel Delete Kits) |
Stock (Original Configuration) |
| Horsepower |
Increased by 5-200+ HP depending on tuning and modifications, unlocking more power and torque for better performance. |
Standard factory output; limited by emissions controls. |
| Fuel Economy |
Improved by 3-5+ MPG or more (e.g., from 15 to 26 MPG reported), due to no regen cycles and reduced restrictions. |
Standard efficiency; impacted by regen processes and DEF usage, potentially lower overall. |
| Maintenance Cost |
Lower long-term costs; eliminates expensive repairs for emissions components like DPF, EGR, and SCR. |
Higher; emissions systems can fail and require costly fixes (e.g., $6,000+ for replacements). |
| Reliability |
Enhanced; removes failure-prone parts, reducing issues like clogging and breakdowns for better engine longevity. |
Potentially lower due to emissions-related failures, though modern systems are more reliable. |
| Installation |
Requires professional installation, tuning, and hardware (cost: $1,000-$5,000+); not DIY-friendly for most. |
None required; factory setup. |
| Exhaust Gas Temperature |
Generally lower; cooler intake air and better exhaust flow reduce EGTs, benefiting turbo and engine health. |
Higher; EGR recirculation increases temperatures, potentially stressing components. |
| Legal Status |
Illegal for on-road use in the US; violates federal emissions laws (EPA); off-road or racing only. |
Fully legal and compliant with emissions regulations. |
| Warranty Impact |
Voids manufacturer warranty on engine, emissions, and related systems; no coverage for modifications. |
Full warranty coverage as per factory terms. |
| Resale Value |
Potentially lower; may deter buyers due to legal issues, modifications, and perceived risks. |
Higher; stock condition appeals to more buyers and maintains value better. |

Diesel Delete Kit Buying Guide
To ensure a smooth upgrade and get your truck back on the road faster, follow this professional guide to get the perfect Diesel Delete Kit.
1. Identify Your Specific Platform
Before ordering, confirm your truck's core specs. Small differences in year or model change the hardware required.
- Engine Type: Are you a Ford Powerstroke (6.7L, 6.4L), Dodge Cummins (6.7L), or GMC Duramax (L5P, LML)?
- Year & VIN: Some mid-year changes (like 2007.5 or 2011) dictate whether you need DEF/SCR delete components.
- Configuration: Is it a Standard Pickup or a Cab & Chassis? Exhaust pipe lengths and bends are not interchangeable.
2. Choose Your Delete Level
Decide if you want a targeted fix or a total transformation:
- The Full Delete (Recommended): An All-in-One Kit that removes the DPF, EGR, and DEF systems. This is the most popular choice for maximum reliability.
- Stage 1: DPF/DEF removal only (improves exhaust flow).
- Stage 2: Adds the EGR delete (lowers engine temps and stops soot recirculation).
3. Don't Forget the Tuner
Hardware requires software. If you remove physical filters without a delete tune, your truck will enter limp mode immediately.
- Handheld Tuners: Like Ez Lynk or Mini Maxx, these reprogram your ECM to recognize the missing sensors.
- ECM Unlock: If you drive a newer GMC L5P (2017+) or RAM (2019+), your computer may need an unlock before it can accept a tune.
Select Your Exhaust Size
- 4-Inch Pipe: Standard for most builds; provides a classic straight pipe sound and plenty of flow for daily driving.
- 5-Inch Pipe: Best for high-horsepower builds or those wanting a deeper, more aggressive exhaust note.
Pro Tip: If you want a 100% guaranteed fit without the headache of matching individual parts, always go with an All-in-One delete Kit. It includes the exhaust, the plates, and the tuner pre-loaded with the correct files.
How to Install a Diesel Delete Kit
Installing a Diesel Delete Kit is a precision process that transforms your engine’s breathing and filtration system. While the exact steps vary between Ford Powerstroke, Dodge Cummins, and GMC Duramax platforms, the general workflow remains consistent. Most kits are designed as bolt-on solutions, meaning they utilize factory mounting points for a cleaner, more secure fit.
Installation Steps
-
Software Preparation (The Tune): Before any hardware is touched, you must install the Performance Tuner. This reprograms the ECM to function without emissions sensors. Never remove hardware before installing the tune, as this will trigger limp mode.
-
Exhaust System Removal: The restrictive factory DPF (Diesel Particulate Filter) and SCR/DEF components are unbolted and removed. This creates the necessary space for your new high-flow straight pipe or performance exhaust.
-
EGR Bypass/Delete: For a full delete, the EGR (Exhaust Gas Recirculation) cooler and valves are either bypassed or removed using precision-cut plates. This prevents hot, dirty soot from re-entering your intake manifold.
-
Sensor Management: All factory exhaust sensors are either disconnected or plugged, depending on the specific tuning software requirements for your engine model.
-
Final Inspection & Test: Once the hardware is secured, a final check of all clamps and bolts is performed. Start the engine and verify that there are no check engine lights or exhaust leaks.
Note: Every EngineGo kit includes a comprehensive, model-specific guide to ensure your installation is seamless and your fitment is guaranteed. For technical deep-dives, step-by-step photos, and specific torque specs, you can find detailed information under the Installation Guide tab on every product page.
