Built For Power And Tuned For Performance Gains

The MBRP S6287SLM Exhaust System is a 4-inch DPF-back setup designed specifically for 2011–2016 Ford F-250 and F-350 trucks equipped with the 6.7L Power Stroke. This system eliminates the factory muffler, creating a straight-through path that significantly reduces backpressure and maximizes exhaust flow. The result is lower exhaust gas temperatures, improved torque, and a sharper throttle response, especially under load or towing conditions. It retains the diesel particulate filter, keeping the truck emissions compliant while still boosting performance. The system is crafted to work with factory mounting points, making installation straightforward with no cutting or welding required. While it doesn’t include a tip, this gives drivers the flexibility to choose their own look or run it stealth. MBRP includes all necessary clamps and hardware for a true bolt-on experience. Whether you're building a workhorse or weekend warrior, this system is engineered to keep things cool, fast, and flowing.
