2nd Gen 5.9L Cummins Exhaust System

Reduce restrictive backpressure, lower exhaust gas temperatures (EGTs), and maximize the performance of your 1994-1998 2nd Gen 12V Cummins with heavy-duty exhaust systems and components. Factory exhaust tubing is narrow, restrictive, and prone to trapping heat under heavy towing and high-boost conditions, choking your 12-valve diesel engine of valuable horsepower. Upgrading to a high-flow, mandrel-bent exhaust system or individual performance components ensures optimal exhaust scavenging, improved turbo spool-up, and long-lasting durability. Shop precision-engineered exhaust upgrades built for exact factory fitment and extreme-duty performance.
