4''/5'' DPF & Cat Delete Race Pipe

The Spelab 4''/5'' DPF & Cat Delete Race Pipe is engineered for 2008-2010 Ford 6.4L Powerstroke diesel engines, specifically for F-250, F-350, and F-450 Super Duty trucks, including Crew Cab Short Bed, Crew Cab Long Bed, and Cab & Chassis configurations. Constructed from magnetic T-409 stainless steel with a 2mm thickness, this pipe offers enhanced durability and heat resistance. The mandrel-bent construction maximizes flow efficiency, allowing your diesel engine to breathe more freely. By removing the DPF and catalytic converter, this delete pipe addresses issues like increased backpressure caused by clogging, which can disturb fuel flow and reduce mileage. Removing the DPF eliminates the need for regular maintenance such as cleaning or replacement and prevents costly DPF failures. Users can expect a significant increase in fuel mileage, potentially from 13-14 mpg to 18-19 mpg combined, especially when paired with an ECU remap. The increased exhaust flow also contributes to improved engine performance. For optimal results, a DPF delete capable tuner is required to prevent check engine lights or diagnostic trouble codes. Installation is estimated to take about 1 hour with basic hand tools, though cutting may be necessary for shorter wheelbase configurations. Clamps, hangers, and hardware are included, though some factory hardware may need to be reused. This product is intended for off-road use only, as DPF removal is illegal for on-road vehicles in most regions. When choosing between the 4" and 5" options, the 4" pipe is better for mild to moderate tunes, retaining some backpressure for low-end torque, while the 5" pipe is best for high-horsepower builds, maximizing flow for reduced EGTs and top-end power.
