Built For Flow And Tuned For Performance

The MBRP S6284AL 4-Inch Filter-Back Installer Series Exhaust System is engineered specifically for 2011–2014 Ford F-250 and F-350 Super Duty trucks equipped with the 6.7L Power Stroke diesel engine. This system uses high-flow, mandrel-bent 4-inch aluminized steel tubing that improves exhaust velocity while reducing backpressure. By maintaining the factory diesel particulate filter, it stays emissions compliant while still offering better airflow and cooler exhaust gas temperatures. The single side exit configuration mirrors the OEM setup for a clean appearance and straightforward installation using the truck’s original hangers. MBRP includes all required clamps and hardware, so there’s no need for custom fabrication or cutting. The result is a noticeable improvement in torque and throttle response, especially under load. It also helps reduce strain on the turbo, contributing to longer engine life and more efficient towing. This system is ideal for truck owners who want dependable gains without overcomplicating the process.
