Engineered For Endurance Performance And Cooler Operation

The MBRP S6130409 4 Inch Filter Back Single Side Exit System is a performance-driven solution built specifically for the 2007–2009 RAM 2500 and 3500 6.7L Cummins platform. Constructed from T409 stainless steel, this system offers long-lasting durability and excellent resistance to corrosion in tough climates. It features mandrel-bent tubing that maintains consistent diameter through every curve, which reduces backpressure and allows exhaust gases to flow more freely. As a filter-back system, it connects behind the factory diesel particulate filter, so it stays emissions compliant while still boosting performance. This improved flow leads to lower exhaust gas temperatures under heavy throttle or while towing, protecting key components like the turbo and EGR. Designed to fit using factory hanger locations, installation is straightforward and requires no welding. The deep, aggressive tone is pure MBRP, giving your truck a voice that matches its capability. If you need a system that’s built to work hard and last long, this one checks every box.
