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 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. DPF delete eliminates these extra maintenance tasks and reduces repair costs.

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

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 unnecessary. 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.

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

4. Depending on your model, you may need to re-use some factory hardware, 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 compatibility with your engine’s system.

Cost and Legality - What to Know About the Duramax DPF Delete Kit

Cost Details

FAQ

Q: Will a DPF delete affect my engine?

A: Yes, but in a good way—when done correctly. Removing the DPF reduces exhaust backpressure, which helps your engine breathe better, respond faster, and run more efficiently. However, proper tuning is essential after deletion to avoid error codes and ensure smooth performance.

Q: What’s the difference between a DPF delete and a DEF delete?

A:

• DPF delete removes the diesel particulate filter, which reduces backpressure and improves airflow and fuel efficiency.

• DEF delete disables the diesel exhaust fluid system, which mainly affects emissions but less impacts performance.
  A DPF delete kit offers more noticeable results for power and MPG gains.

Q: Do I need tuning after a DPF delete?

A: Yes. A compatible L5P tuner is required to recalibrate the engine after DPF removal. Without tuning, your truck will likely show check engine lights, go into limp mode, or perform poorly.

Q: What is a DPF race pipe?

A: A DPF race pipe (also known as a DPF delete pipe) replaces only the section of your exhaust that contains the DPF. It allows better flow while keeping other parts like the downpipe and tailpipe intact.

Q: What’s the difference between DP-back, downpipe-back, and turbo-back systems?

A:

• DP-back (Downpipe-back): Replaces everything after the downpipe—including mid-pipe, muffler, and tailpipe.

• Turbo-back: Replaces the exhaust system from the turbocharger outlet to the tip, offering maximum flow.
  Choose DP-back for ease of install, or turbo-back for full airflow gains.

Q: What material are your delete pipes made from?

A: All our DPF delete pipes are made from 409 stainless steel, which is strong, corrosion-resistant, and ideal for high-temperature diesel applications.

Q: Will I need extra parts to install the DPF delete kit?

A: No. Our kits are all-inclusive and come with every part you need—pipes, clamps, hangers, and installation hardware. There are no surprises or extra purchases required.

Q: Will your DP-back pipe fit my factory downpipe?

A: Yes. Our L5P DP-back kits are designed to bolt directly to your stock downpipe using factory hardware for a seamless fit.

Q: Why doesn’t this DPF delete kit work on cab & chassis models?

A: Cab and chassis trucks have longer wheelbases and different exhaust routing. You’ll need a specially sized pipe. We clearly mark compatibility on each product—look for “Cab & Chassis” in the title, or contact us to confirm.
