Make Your Cummins Sound Like The Powerhouse It Is

If your 2003–2004 Dodge RAM 2500 or 3500 with the 305HP 5.9L Cummins still has the stock exhaust, it’s time to bring it to life with the MBRP S6104AL Turbo Back Exhaust System. This system unleashes a bold, deep tone that matches the strength of your truck and gives it the presence it deserves on the road or jobsite. Built with a full turbo-back design and a single side exit, it opens up your exhaust flow and makes a noticeable difference in performance and throttle response. It’s ideal for drivers who want a more aggressive sound and feel, without going overboard. Made from cost-effective aluminized steel, it delivers long-lasting reliability at a wallet-friendly price, especially for those driving in dry to moderate climates.

Designed To Maximize Flow Reduce Heat And Improve Power

The MBRP S6104AL system is engineered for the 305HP version of the 5.9L Cummins in 2003–2004 RAM 2500 and 3500 trucks, replacing the entire factory exhaust with a high-flow, 4-inch turbo-back design. This system significantly reduces backpressure and improves the speed at which exhaust gases exit, which leads to cooler exhaust gas temperatures under load. That makes it especially useful for towing, heavy hauling, or long climbs where engine temps can spike. The aluminized steel construction is corrosion-resistant and provides excellent durability for the price, making it a great option for daily use and work-duty rigs. The system uses mandrel-bent tubing for smooth, unrestricted flow and is designed to bolt directly to existing factory hanger locations. It comes with all clamps and hardware needed for installation, so there’s no need for cutting or welding in most setups. This system is also tailored for trucks not equipped with emissions devices, making it a go-to for performance builds. It’s a functional and proven upgrade for diesel owners looking for dependable gains in power, efficiency, and sound.
