DPF Delete Race Pipe

The Spelab DPF Delete Race Pipe is constructed from T-409 stainless steel with a 2mm thickness for durability and heat resistance. Available in 4-inch and 5-inch diameters, this pipe is designed to replace the factory Diesel Particulate Filter (DPF) on 2011-2024 Ford 6.7L Powerstroke F-250, F-350, and F-450 models. The product aims to reduce exhaust restriction, supporting tuned builds for better flow, sound, and serviceability. Installation is described as straightforward for experienced DIYers, typically taking about an hour with basic hand tools. However, it requires lifting the truck and removing the OEM DPF and catalytic converter, with professional installation recommended for those lacking the necessary tools or experience. Clamps, hangers, and hardware are included, though some factory hardware may need to be reused. Cutting might be required for shorter wheelbase configurations. A crucial aspect of installing this DPF delete pipe is the requirement for a compatible DPF-off tuner. This is necessary to prevent check engine lights and diagnostic trouble codes that arise from the removal of emissions-related sensors. Running the delete pipe without proper tuning can lead to performance issues or potential engine damage. The product is explicitly for off-road or racing use only and violates U.S. EPA and CARB emissions regulations; use on public roads may result in fines. This specific DPF delete pipe does not fit Cab & Chassis models. The 5-inch version is noted for delivering a deeper tone with less drone compared to the 4-inch pipe, making it a preference for towing and high-performance builds.
