2nd Gen 24V 5.9L Cummins Exhaust System

Maximize exhaust gas velocity, significantly lower exhaust gas temperatures (EGTs), and unlock a deep, aggressive diesel tone on your 1998.5–2002 2nd Gen 5.9L 24V Cummins with a high-flow performance exhaust system. Factory exhaust piping features restrictive mandrel bends, narrow diameters, and restrictive mufflers that trap heat and choke your turbocharger's ability to spool efficiently. Upgrading to a mandrel-bent turbo-back or cat-back exhaust system improves scavenging, reduces backpressure, and handles high-horsepower output with ease. Shop top-tier exhaust systems and components engineered for exact factory fitment and extreme-duty durability.
