Designed To Improve Flow And Handle Heavy Loads

The MBRP S6130AL 4 Inch Filter Back Single Side Exit Exhaust System is engineered to give your 2007–2009 6.7L Cummins better performance without compromising emissions equipment. As a filter-back design, it connects behind the factory diesel particulate filter and maintains street legality while still boosting airflow. The 4-inch mandrel-bent tubing provides a smoother path for exhaust gases, which helps reduce backpressure and lower exhaust gas temperatures, especially useful under towing or work conditions. Aluminized steel construction offers a strong balance of heat resistance and affordability for drivers in dry or moderate climates. With improved flow, you can expect better throttle response and reduced strain on the turbo system. The system uses factory hanger locations, allowing for a straightforward bolt-on installation without welding or modifications. It also includes all required clamps and hardware to ensure a secure, leak-free fit. Built for performance-minded drivers who rely on their trucks daily, this system adds reliability, efficiency, and sound all in one.
