2017-2025 3''/3.5'' Downpipe Exhaust For 2017-2025 L5P Chevy GMC 6.6L Duramax Diesel

Fitment:

• 2017-2025 Chevrolet Silverado & GMC Sierra 2500 & 3500HD 6.6L Duramax pickup trucks

Will not fit Cab & Chassis trucks.

What does a downpipe do?

The downpipe on your turbocharged vehicle is directing the exhaust gases out of the turbine housing into the exhaust system. An aftermarket downpipe will typically be larger in diameter and either uses a high-flowing catalytic converter or remove the catalytic converter altogether.

By removing the factory downpipe and replacing it with a high flowing unit you are allowing the turbo to more efficiently move gases away from the turbine which creates more power. Since the factory restrictions are now gone you can increase the boost on the vehicle as the factory downpipe is a choking point for performance.

Absolutely. The package includes a complete EGR delete kit, DPF delete race pipe, downpipe, up-pipe, and a CAN BUS plug tailored for the 2017–2025 L5P. This is a full delete solution, engineered for performance and reliability.

Q. Will I need to tune my ECU after installing this kit?
Yes. A custom ECU tune is required after installation to disable the EGR/DPF functions and related trouble codes. We strongly recommend pairing this kit with a quality tuning solution to fully unlock the benefits and prevent warning lights.

Q. Are there any differences between the 2020 L5P Delete Kit and other model years?
The core components remain consistent, but the CAN BUS plug design varies slightly between 2017–2019 and 2020–2025 models. DPFExhaust provides year-specific parts to ensure plug-and-play compatibility for your truck.

Q. What impact does deleting the EGR and DPF have on the engine and turbo system?
Removing the EGR and DPF reduces exhaust backpressure, improves turbo response, lowers combustion temps, and significantly reduces carbon buildup. This results in better reliability and longer life for your engine and turbo system.

Q. How much horsepower and torque gain can I expect with this kit?
Depending on your tune and setup, you can expect gains of 50-100+ horsepower and 100-150 lb-ft of torque. Results will vary based on vehicle condition and tuning strategy.

Q. Is this kit street-legal?
This product is intended for off-road, competition, or agricultural/industrial use only. Removing emissions equipment is illegal on public roads in many states. Please check and comply with your local regulations before purchase or installation.

Q. How difficult is the installation? Can I do it myself?
Installation requires solid mechanical knowledge and experience. Because it involves exhaust modification and ECU tuning, we highly recommend having a professional mechanic perform the installation to ensure everything runs safely and correctly.

Q. What materials are used in DPFExhaust’s L5P Duramax Delete Kit?
We use high-grade stainless steel for the downpipe and DPF delete pipes, with precision laser-cut flanges and TIG welding to ensure durability, corrosion resistance, and long-lasting performance under heavy-duty conditions.

Q. After installing the 2017-2025 L5P 6.6 Duramax Delete Kit, will there be any extra maintenance needed?
Overall, maintenance becomes easier. Without DPF regeneration and EGR soot buildup, oil contamination is reduced, and the turbo and intake system stay cleaner. We recommend periodic inspection of exhaust flanges and welds for tightness and integrity.
