304 Stainless Steel Up-Pipe

The Spelab High-Flow Up-Pipes are engineered to replace the restrictive stock components in 2020-2025 Ford 6.7L Powerstroke F250, F350, F450, and F550 models. These up-pipes efficiently route exhaust gases from the exhaust manifolds to the turbocharger, eliminating factory restrictions. The improved airflow design boosts turbo turbine force, increases boost pressure, and unlocks the truck's full engine performance and responsiveness. Built with high-grade 304 stainless steel, these up-pipes provide exceptional durability, full corrosion resistance, and long-lasting performance, capable of withstanding extreme high-heat and heavy-duty driving conditions. The upgraded internal design features enlarged pipe diameters and smooth passages that remove stock flow limitations, thereby reducing exhaust back pressure, increasing exhaust gas velocity, and delivering maximum airflow to the turbocharger. This leads to faster turbo spool and reduced turbo lag, resulting in quicker throttle response and more immediate power delivery. Furthermore, this high-flow design promotes better exhaust scavenging, which lowers Exhaust Gas Temperatures (EGTs). Reduced exhaust heat protects the engine and turbo assembly, enhancing reliability during demanding towing and heavy-duty use. These up-pipes are an ideal upgrade for trucks running EGR and DPF delete systems, as well as for tuned vehicles with upgraded injectors or larger turbo setups. They are also essential for heavy towing and high-load operations. What's in the Box: Driver Side Up-Pipe, Passenger Side Up-Pipe, Gasket.
