2017-2025 L5P Duramax 6.6L 4" Race Pipe for Chevy Silverado/GMC Sierra 2500HD/3500HD - DPF & CAT Replacement
Unleash the true potential of your 2017–2024 L5P 6.6L Duramax with our high-performance DPF delete pipe. Precision-engineered to eliminate restrictive factory filters, it dramatically lowers exhaust gas temperatures (EGTs), enhances turbo spool-up, and improves throttle response. Its mandrel-bent design ensures smooth, efficient exhaust flow—so your diesel can breathe freely. Ideal for off-road use, this upgrade delivers stronger power and reduced maintenance.
- It removes the need to service the DPF at regular intervals (cleaning, replacement)
- A DPF delete will remove the possibility of a DPF failure which could cause expensive diesel repairs
- Due to less exhaust backpressure, the DPF delete increases exhaust flow and therefore increases the performance of your motor!
- Paired with an ECU remap, the DPF delete is proven to increase power and torque for all vehicles
