Collection: 5" Exhaust for 5.9 Cummins (2003–2007) | Turbo Back & Race Systems
5" Exhaust Systems for 5.9L Cummins (2003–2007)
Upgrade your diesel truck with a 5-inch exhaust system for the 5.9L Cummins, designed to deliver maximum airflow, lower exhaust gas temperatures, and a deeper, more aggressive sound. These exhaust systems are built specifically for 2003–2007 Dodge Ram 2500 and 3500 5.9 Cummins engines, making them a top choice for performance-driven diesel owners.
A larger 5-inch diameter exhaust significantly reduces backpressure compared to smaller systems, allowing your turbocharger to spool faster and your engine to breathe more efficiently under load.
