Built For Flow Longevity And Everyday Performance

The MBRP S6130BLK 4 Inch Filter Back Exhaust System is designed to improve performance and durability for 2007–2009 Dodge RAM trucks equipped with the 6.7L Cummins engine. As a filter-back system, it connects behind the diesel particulate filter, making it emissions compliant while still delivering measurable gains in airflow and efficiency. The 4-inch mandrel-bent tubing helps reduce restriction, which lowers exhaust gas temperatures and enhances overall turbo response. This system is especially helpful under heavy loads or long hauls, where cooler temperatures and improved flow can protect engine components and sustain consistent power output. Its black-coated aluminized steel construction adds corrosion resistance and a custom appearance without compromising value. All factory hangers are utilized for a hassle-free bolt-on installation, with no welding required. Whether you're hauling equipment, hitting the highway, or upgrading your weekend driver, this system is a dependable, emissions-friendly way to boost your truck's performance and sound. It’s practical, efficient, and built to keep up with your truck’s demands.
