4"/5" DPF Delete Race Pipe

The Spelab 4"/5" DPF Delete Race Pipe is engineered for off-road applications on 2011-2024 Ford 6.7L Powerstroke Super Duty trucks (F-250, F-350, F-450). This race pipe replaces the factory Diesel Particulate Filter (DPF) and catalytic converter, significantly reducing exhaust backpressure and restriction to enhance exhaust flow, sound, and overall performance. Constructed from durable T-409 stainless steel with a 2mm thickness, this pipe features mandrel-bent construction to ensure maximum flow efficiency. The kit includes clamps, hangers, and hardware, with installation estimated at approximately 1 hour using basic hand tools. Cutting may be required for shorter wheelbase configurations. For optimal performance and to prevent check engine lights, a DPF-delete capable tuner is required. Benefits include potential increases in fuel mileage, with users reporting an average gain of 5-6 MPG, and eliminating the need for costly DPF cleanings or replacements. By reducing exhaust backpressure, the DPF delete pipe enhances overall engine performance when paired with an ECU remap. It is important to note that this modification is intended for off-road/racing use only and violates U.S. EPA and CARB emissions regulations, meaning it will not pass emissions testing. Use on public roads may result in fines and penalties. This product does not fit Cab & Chassis models. Professional installation is recommended for those lacking the necessary tools or experience. A compatible DPF-off tune is mandatory to prevent diagnostic trouble codes and ensure proper engine operation after installation.
