Built To Flow Freely And Cool Under Pressure

The MBRP S6108P Cat Back Exhaust System is engineered to increase efficiency and durability for 2004–2007 Dodge RAM 2500 and 3500 trucks with the 5.9L Cummins. It replaces the factory exhaust from the catalytic converter back, using 4-inch mandrel-bent tubing to reduce restrictions and promote better airflow. That improvement helps reduce exhaust gas temperatures, especially under heavy loads or extended highway driving. This system is ideal for towing applications where managing heat and keeping power consistent is essential. Made from aluminized steel, it provides a reliable and cost-effective alternative to stainless without sacrificing performance for dry to moderate climates. The system also boosts turbo spool and low-end torque, delivering noticeable gains without the need for additional tuning. Installation is straightforward, using factory hanger locations and including all clamps and hardware needed. It’s a solid solution for diesel owners looking to upgrade performance and tone without breaking the bank.
