4" DPF Delete Race Pipe

The Spelab 4'' DPF Delete Race Pipe is engineered for off-road use in 2011-2024 Ford 6.7L Power Stroke F-250, F-350, and F-450 Super Duty trucks. This performance exhaust upgrade eliminates the factory Diesel Particulate Filter (DPF) and catalytic converter, which are known to cause increased backpressure, reduced fuel economy, and higher maintenance costs. By removing these restrictions, the DPF delete pipe facilitates improved exhaust flow, potentially leading to better fuel mileage and supporting tuned engine configurations. Constructed from T-409 stainless steel with a 2mm thickness for robust durability and heat resistance, this pipe features mandrel-bent construction to ensure maximum flow efficiency. The 4-inch diameter is recommended for stock to lightly-modified trucks, offering a balance of flow and a less aggressive exhaust note compared to larger diameter pipes. Clamps and hardware are included, though some factory hardware may need to be reused. Crucially, installing a DPF delete pipe requires a compatible DPF-off tuner to prevent check engine lights and diagnostic trouble codes, ensuring proper engine operation. This modification is intended for off-road and racing use only, as it violates U.S. EPA and CARB emissions regulations and will cause failure in emissions testing. Furthermore, performing this modification may void the vehicle's powertrain warranty. It's important to note that this specific variant does not fit Cab & Chassis models; a different SKU (SPES08793-ES08019SP) is required for those applications.
