Give Your Cummins The Sound And Swagger It Deserves

If your 2004–2007 Dodge RAM 2500 or 3500 with the 5.9L Cummins is still breathing through its stock exhaust, the MBRP S6108AL Cat Back System is the upgrade that gives it the voice and muscle it was built for. With a deep, commanding tone and a noticeable bump in throttle response, this system transforms your truck’s everyday performance and driving experience. You’ll feel stronger low-end torque and smoother acceleration, especially when you’ve got a trailer behind you or a load in the bed. Made from aluminized steel, it balances strength and value perfectly for those driving in dry to moderate climates. The single side exit keeps things looking clean while adding just enough presence to turn heads. Whether you’re rolling through town or climbing mountain grades, your Cummins will finally sound as tough as it performs. It’s a no-nonsense, high-impact upgrade that brings out the best in your diesel.

Designed To Flow Cooler Run Stronger And Install Clean

The MBRP S6108AL 4 Inch Cat Back Exhaust System is engineered for the 2004–2007 5.9L Cummins to reduce restriction, improve efficiency, and help your turbo perform more consistently under load. The 4-inch mandrel-bent tubing provides a smoother path for exhaust gases, lowering backpressure and reducing exhaust gas temperatures in demanding driving conditions. This helps improve horsepower, torque, and turbo spool-up while promoting better fuel economy during extended towing or highway use. Because it’s a cat-back system, it retains your factory catalytic converter while still making room for noticeable gains in sound and airflow. Constructed from aluminized steel, this system is ideal for budget-conscious drivers who want reliable performance in typical daily driving environments. It installs easily with a bolt-on design using factory hanger locations and includes all clamps and hardware needed. The single side exit design maintains an OEM-style appearance while delivering a more aggressive sound signature. It’s a smart upgrade for any Cummins owner looking to keep things efficient and powerful without overcomplicating the install.
