Benefits of DPF Delete - Why GMC DPF Removal is Worth It

Boost Fuel Efficiency
Removing the DPF dramatically reduces exhaust backpressure, allowing fuel to flow more freely. This can raise your fuel economy from around 13-14 mpg up to an impressive 18-19 mpg. More miles per gallon means more savings—and more driving freedom.

Reduce Maintenance Needs
The standard DPF requires regular cleaning and replacement to stay functional. With DPF delete, you eliminate these extra maintenance tasks and cut down on repair costs.

Increase Power and Torque
DPF removal frees up your engine to breathe and boosts overall power output, especially noticeable in off-road driving. With this kit, you’ll feel the added torque and responsiveness, giving you a true performance upgrade that you can feel with every mile.

Installation Guide - How to Install the Duramax DPF Delete Kit

Tools and Preparation
Installing this DPF delete kit requires only basic hand tools, making it perfect for a DIY setup in your garage. An automotive lift will make the job quicker, but it’s not required. If your model has a shorter wheelbase, you might need to make a few cuts for the perfect fit.

Installation Steps

1. Gather all necessary tools, and position your truck in a safe working environment.

2. Attach the DPF delete kit to the exhaust system and secure it in place.

3. Use the provided clamps and hardware to complete the connection.

4. You may need to re-use some factory hardware depending on your model, so keep it handy for a secure fit.

Important Note: Tuning Requirement
Since removing the DPF changes the emissions system, you’ll need a DPF-delete-compatible tuner to prevent any check engine lights or diagnostic codes. This tuning step ensures smooth operation and full compatibility with your engine’s system.

Q: What’s the difference between DEF delete and DPF delete?
DEF delete involves removing the diesel exhaust fluid system, while DPF delete removes the diesel particulate filter (DPF). Both impact emissions, but DPF delete tends to have a more direct impact on fuel economy and power.

Q: Do I still need tuning after DPF delete?
Yes, tuning is crucial after DPF removal to ensure your engine continues to run properly and that no warning lights or diagnostic codes interfere with performance.

Q: What does "Turbo-back" mean?

A: This means that the exhaust system runs from the turbocharger all the way to the end of the exhaust pipe, replacing everything from the turbocharger outlet back. This typically includes the downpipe, mid-pipe, catalytic converter (if present), muffler, and tailpipe.

Q: What is your DPF made from? Stainless steel or aluminum?
