Unleash The True Voice And Muscle Of Your Cummins

If your 2003–2004 Dodge RAM 2500 or 3500 with the 5.9L Cummins is still breathing through the stock exhaust, it’s time to give it the performance and sound it was built for. The MBRP S61140P P Series Turbo Back Exhaust System opens up the flow from the turbo all the way out, letting your diesel breathe easier and work harder. Right out of the box, you’ll notice a throatier, more aggressive exhaust note that lets people know you’re driving a serious truck. But it’s not just about sound—this system also helps improve throttle response and torque, especially when towing or hauling under load. The aluminized steel build offers strong reliability for daily drivers and weekend warriors who want more grunt without overspending. A clean single side exit gives it that sharp factory-finished look with added muscle underneath. If you’re chasing more performance, better tone, and a truck that responds like it should, this setup makes an immediate difference.

Engineered For Flow Performance And Thermal Efficiency

The MBRP S61140P P Series Turbo Back Exhaust System is built to optimize exhaust flow, reduce restriction, and improve overall efficiency for your 2003–2004 5.9L Cummins. It features 5-inch mandrel-bent tubing, which provides a consistent diameter through every bend for smooth, uninterrupted exhaust gas evacuation. That design helps lower exhaust gas temperatures and backpressure, especially important when pulling heavy loads or running long highway stretches. Made from aluminized steel, this system provides dependable strength and corrosion resistance in dry to moderate climates, making it a practical choice for hardworking trucks. It’s a full turbo-back system, so it removes the factory muffler and tail section, allowing your engine to expel hot air faster and more efficiently. The included clamps and hardware ensure a hassle-free installation that bolts directly to factory hanger locations. This system is best suited for non-emissions-equipped or off-road builds where airflow and performance are the priority. If you want a system that balances price, power, and practical function, this one is built to perform.
