DPF/EGR/DEF Delete Kit

The SPELAB DPF/EGR/DEF Delete Kit is a comprehensive package engineered for 2017-2023 L5P 6.6L Duramax engines, aimed at maximizing performance and reliability. This kit facilitates a full emissions delete, removing the DPF and EGR systems to allow for unrestricted airflow, lower engine temperatures, and reduced turbo backpressure. This not only contributes to longer engine life by minimizing carbon buildup but also enhances fuel economy by eliminating forced regens and DEF usage, potentially improving MPG by 2-5+. The kit includes a high-performance tuner with an OBDII Flash Delete Tuning Interface, offering tune adjustments through the OBDII port and supporting SOTF (Shift-on-the-Fly) tuning via factory steering wheel controls. The package contains an EGR Delete Kit, DPF Delete Kit, a Tuner Delete interface with tune and credits, an Unlock Kit, and an exhaust system (options for 4" DPF Race, 4" Downpipe-Back, or 5" Downpipe-Back). Some components and accessories may vary based on the order. This kit is compatible with 2017-2023 L5P 6.6L Duramax Diesel GMC Sierra 2500/3500 HD and Chevrolet Silverado 2500/3500 HD models. However, it is explicitly not compatible with cab and chassis models. Additionally, if your truck already has aftermarket exhaust or previous tuning, ensure compatibility as this may require a different package. The SPELAB 6.6L Duramax L5P DP-Back exhaust system must be used in conjunction with their downpipe, as the factory downpipe has an integrated SCR assembly. **Important Note:** These products are intended for off-road, racing, or closed-course use only. Customers are responsible for verifying and complying with all local, state, and federal emissions regulations prior to purchase, installation, or use. Installing this kit may void your vehicle's warranty, and professional installation is recommended for optimal setup and performance, despite the availability of detailed installation guides.
