Engineered Flow And Durability For Demanding Diesel Performance

At its core, the MBRP S61340409 is a filter back exhaust system engineered to improve efficiency while maintaining compatibility with the factory DPF on 2010-2012 RAM 2500 and 3500 6.7L Cummins models. The 5 inch mandrel bent tubing maintains consistent diameter through every curve, which helps reduce backpressure and support optimal exhaust scavenging. This smoother flow can contribute to lower exhaust gas temperatures, especially under load, which is critical for trucks that tow or haul regularly. Furthermore, the T409 stainless steel construction offers excellent resistance to corrosion and thermal fatigue, making it a practical choice for year round use in harsh climates. The bolt on design is tailored to factory mounting points, allowing for a straightforward installation without the need for welding. Each connection is engineered for a secure fit to minimize leaks and vibration over time. Backed by MBRP decades of exhaust development, this system delivers a balanced combination of durability, sound control, and performance focused design that serious diesel owners can appreciate.
