Bully Dog’s new bolt-on Performance DPF for the Ford 6.4-liter Powerstroke features a larger and better-flowing filter to unleash your truck’s potential – legally. Exhaust flow is increased by 17% compared to stock, through a more efficient design and proprietary coating engineered for performance. Realize measurable increases in horsepower and torque using the Bully Dog Performance DPF alone, or go for max gains by pairing it with a Bully Dog tune. Slower soot accumulation and faster-igniting particulate matter means fewer regens and consistent power in between regens. Constructed in North America from 409 and 304 Stainless Steel, the Bully Dog Performance DPF is built to resist weather and corrosion – making it as durable as it is beautiful. The 304 SS V-band clamp provides full filter access for cleaning, meaning it’s the last DPF you’ll ever need to buy. Take back lost efficiency and add performance, all while remaining emissions compliant, with Bully Dog Performance DPF.
