Get The Power Flowing Right From The Turbo

When you’re ready to wake up your 6.7L Powerstroke, replacing that restrictive factory downpipe is one of the best upgrades you can make. The MBRP FS9460 4-Inch Turbo Down Pipe gives your exhaust the freedom it needs to flow better, run cooler, and support stronger performance across the board. Built from durable T409 stainless steel, this downpipe is made to handle the heat and abuse of real-world driving while resisting corrosion along the way. That means whether you're hauling a trailer or laying into the throttle, you're getting a boost in efficiency and response without sacrificing reliability. The 4-inch diameter provides a major airflow improvement, helping reduce backpressure and letting your turbo spool up faster and smoother. Plus, it installs as a direct bolt-on with no major modifications, so you can knock it out in the garage with basic tools. If you want a quick and effective upgrade that brings real gains, this MBRP downpipe delivers.

Built To Outflow Stock And Withstand The Heat

The MBRP FS9460 4-inch downpipe is engineered for 2015–2016 Ford F250 and F350 trucks with the 6.7L Powerstroke, offering a significant upgrade over the stock downpipe in both performance and material quality. Its 4-inch diameter reduces exhaust restrictions between the turbocharger and the exhaust system, resulting in quicker turbo response, improved throttle feel, and cooler exhaust gas temperatures. Constructed from T409 stainless steel, this pipe provides a solid balance of heat resistance and corrosion protection, making it a durable solution for high-heat and high-load applications. The mandrel-bent design maintains consistent flow throughout the entire pipe, maximizing efficiency for both daily driving and heavy-duty towing. It bolts directly into place without the need for cutting or welding, making installation straightforward for experienced installers and DIYers alike. This downpipe is also compatible with most aftermarket exhaust systems, giving you flexibility for future performance modifications.
