Increase flow in the exhaust system of your 2008-2010 Ford 6.4L Powerstroke with theÂ Bully Dog 70000 Performance Diesel Particulate Filter (DPF). The Bully Dog Bolt-On Performance DPF features a larger, and better flowing filter to unleash the potential of your truck, legally! This upgraded DPF increases exhaust flow by 21% compared to stock, through a more efficient design and proprietary coating engineered for performance. You can have measurable increases in horsepower and torque with just the Bully Dog DPF, or you can maximize performance by pairing it with a Bully Dog Tune.Â The Performance DPF slows soot accumulation, and reduces EGT's by up to 12%, while also reducing backpressure up to 44%. This design requires fewer regenerations and keeps your truck at peak performance between regen cycles. To ease maintenance, the Performance DPF is fully serviceable. You can easily access the catalyst components via stainless steel v-band flanges.Â Measurable Performance The Bully Dog Performance DPF is designed to produce measurable performance gains over stock, all while remaining emissions compliant. An advanced, proprietary internal coating coupled with a significantly larger body achieves less restriction than OEM filters. Achieve greater flow with the Performance DPF alone, or pair with a Bully Dog tune for max gains. Fully Serviceable for Longer Lifespan The Performance DPF is designed to be the last DPF you'll ever have to buy. A clogged or inoperable DPF is a maintenance nightmare as it often needs to be cut into to be cleaned or replaced entirely, potentially costing you thousands. The Performance DPF from Bully Dog features innovative construction including V-band clamps that allow easy access and hassle-free serviceability. Its stainless body and polished stainless steel heat shield keep the DPF protected and looking great all backed by Bully Dog's 2-year warranty. Emissions-Compliant Power Gains Developed with performance gains, exhaust regulations, and the environment in mind, the Performance DPF is proven to produce more exhaust flow for your vehicle while remaining emissions-compliant. Slower soot accumulation and faster-igniting particulate matter means fewer regens and consistent power between each regen. Compliance and performance all in one package.
