Frequently Asked Questions

What is a Duramax DPF delete pipe?
A Duramax DPF delete pipe is a direct replacement pipe that removes the factory diesel particulate filter (DPF) from the exhaust system. It is designed for off-road or competition use and significantly improves exhaust flow, turbo efficiency, and overall performance.
Which Duramax engines support a DPF delete pipe?
We offer DPF delete pipes for all major Duramax platforms including LMM (2007.5–2010), LML (2011–2016), and L5P (2017–2023). These pipes are specifically designed to fit each generation and may require tuning support to disable emissions codes.
Do I need custom tuning when installing a DPF delete pipe?
Yes. Installing a DPF delete pipe requires custom ECM tuning to prevent check engine lights, limp mode, or regen cycles. We recommend pairing your delete pipe with a compatible tuner like EZ Lynk or EFI Live that supports off-road tuning.
Will a DPF delete pipe improve fuel economy and horsepower?
In most cases, yes. Removing the DPF reduces backpressure and allows for more efficient exhaust flow, which can lead to noticeable gains in horsepower, torque, and fuel economy—especially when paired with proper tuning.
Is deleting the DPF on a Duramax legal?
DPF deletes are only legal for vehicles used in off-road, race, or agricultural applications. They are not permitted for street or highway use in most regions. Always check local and federal emissions laws before modifying your truck.
What size delete pipe should I choose—3”, 4”, or 5”?
Most LML and L5P delete pipes are 4" for optimal flow and fitment. Larger 5" systems are ideal for high-horsepower builds, while 3" downpipes may be used to connect to existing race systems. Always match pipe diameter to your performance goals and existing setup.
What’s the difference between a DPF delete pipe and a full downpipe-back race exhaust?
A DPF delete pipe replaces only the section containing the diesel particulate filter. A downpipe-back race exhaust replaces the entire exhaust system after the turbo downpipe, including mufflers and tailpipes—for maximum performance gains.
