2011-2019 6.7L Powerstroke 4" DPF & Cat Delete Race Pipe Overview This 6.7 Powerstroke DPF delete race pipe is a 4-inch exhaust upgrade designed for 2011-2019 Ford F-250, F-350, and F-450 Super Duty pickup trucks with the 6.7L Powerstroke diesel engine. It replaces the restrictive factory diesel particulate filter and catalytic converter section with a freer-flowing race pipe. Whether you're building a professional off-road vehicle or looking to get rid of the hassles of factory emission control systems, this racing exhaust will deliver more power, a deeper roar, and a more reliable diesel driving experience. Fitment Information This race pipe fits the following vehicles: 2011-2019 Ford F-250 Super Duty 6.7L Powerstroke 2011-2019 Ford F-350 Super Duty 6.7L Powerstroke 2011-2019 Ford F-450 Super Duty 6.7L Powerstroke Fitment conditions: Does not fit Cab & Chassis commercial style trucks Built from T-409 Stainless Steel for Long-Term Use This 6.7 Powerstroke race pipe is made from T-409 stainless steel with 2mm wall thickness. Compared with standard OEM-style aluminized steel exhaust materials, T-409 stainless steel offers better heat resistance and improved durability for diesel exhaust applications. Comparison Item T-409 Stainless Steel Aluminized Steel Heat Resistance Better suited for high-heat diesel exhaust use More limited under repeated high heat Corrosion Resistance Better long-term resistance to rust and moisture More likely to wear over time Durability Better for long-term diesel exhaust service More suitable for lower-cost replacement use Best Use Performance, off-road, and competition exhaust systems Budget-oriented exhaust replacements Overall Value Stronger balance of durability and long-term value Lower upfront cost, lower long-term durability Improve Exhaust Flow and Reduce Restriction By replacing the stock DPF and catalytic converter with a smoother 4-inch 6.7 Powerstroke race pipe, exhaust gases can flow more smoothly out of the system. A smoother exhaust path helps reduce exhaust back pressure. Furthermore, the smoother 4-inch exhaust path allows for more efficient heat dissipation, helping to maintain lower EGT and better exhaust flow under demanding conditions. Reduce DPF Maintenance and Regeneration Issues One of the main reasons vehicle owners upgrade is to reduce long-term maintenance and costs. Factory-installed DPF systems incur ongoing expenses due to regeneration-related fuel consumption, DPF cleaning, sensor-related issues, and ultimately, replacement costs. Installing a DPF delete kit completely eliminates the factory regeneration process. This means no forced regeneration, no worries about filter clogging, and significantly reduced long-term maintenance costs. Removing the DPF and CAT can save thousands of dollars in fuel and replacement parts costs over the truck's entire lifespan. 6.7 Powerstroke Race Pipe vs Downpipe-Back: How to Choose When choosing between a race pipe and a downpipe-back exhaust, the main difference is how much of the factory exhaust system is being replaced and what kind of build the truck is intended for. A race pipe is typically designed to replace the restrictive DPF and CAT with a simpler, freer-flowing pipe. A downpipe-back system replaces the exhaust from the downpipe rearward, usually with larger tubing and a more complete exhaust routing setup. Comparison ItemRace PipeDownpipe-Back ExhaustMain PurposeReplaces the DPF/CAT section with a freer-flowing pipeReplaces the exhaust system from the downpipe backSystem CoverageMore focused, simpler section upgradeMore complete rear exhaust upgradeExhaust RestrictionReduces restriction in the deleted sectionImproves overall exhaust flow through the rear systemSound ChangeUsually louder and more rawTypically deeper and more complete exhaust tone changeBest ForOff-road or competition builds focused on delete configurationBuyers wanting a more complete exhaust system upgradeInstallation ScopeMore focused replacementBroader exhaust replacement If your goal is to remove the factory-installed restrictive aftertreatment and simplify the system, a racing exhaust is often a more straightforward choice. If you want a more complete exhaust system upgrade and broader changes to flow, sound, and overall system layout, a 6.7 Powerstroke downpipe-back exhaust system might be a better option. Important Notes Before and After Installing This Race Pipe A tuner is not included; users can choose a tuner compatible with this removed exhaust. Tuning Required: Removing the original DPF and CAT will result in fault codes, and if not properly tuned, the vehicle will enter limp mode. Therefore, installing this exhaust system requires a custom tuner capable of removal and tuning. FAQs Do I need a tuner to remove the racing exhaust for this 4-inch DPF and catalytic converter for the 6.7 Powerstroke engine?Yes. Removing the original DPF and catalytic converter will cause the vehicle's ECU to issue diagnostic codes and enter limp mode. You must use a professional tuner to recalibrate the ECU and electronically disable the emissions system.Is this exhaust system suitable for my cab-over chassis truck?No. This 4-inch racing exhaust is only compatible with standard F-250, F-350, and F-450 pickup trucks (short/long bed double cab). It is not a perfect match for the chassis and piping of cab-over commercial trucks.What is the return policy if there is a problem with the product?We are confident in the quality of this racing exhaust. We offer a 45-day return and money-back policy if you encounter any problems during use. If you are not satisfied or the product is defective, you can return it within 45 days of purchase.Is technical support provided during installation?Yes, of course. We offer comprehensive technical support to ensure a smooth installation. You can contact us by email or phone for real-time troubleshooting assistance. Additionally, we provide a detailed illustrated installation manual to guide you through the entire installation process.Will this make my truck louder?Yes. Removing the DPF will increase the sound. Compared to the factory exhaust system, a 4-inch racing exhaust typically provides a deeper, more aggressive exhaust note. Read More
