The SPEtuner 4-Inch High-Flow Turbo-Back Performance Exhaust System is heavy-duty engineering custom-built for 1994–2002 Dodge Ram trucks equipped with the iconic 12-Valve and 24-Valve 5.9L Cummins turbo diesel engines.\u003c\/p\u003e\n\u003cp\u003eThe factory exhaust system on these classic trucks is an aging, rust-prone 3-inch bottleneck that severely chokes off turbine exit velocity and traps intense heat right at the manifold. This premium, mandrel-bent straight system connects directly to your turbocharger outlet and expands to a high-volume 4-inch uniform body. By replacing the restrictive OEM muffler and stock piping with a true straight-through path, you maximize airflow, plunge Exhaust Gas Temperatures (EGTs), and awaken that legendary Cummins inline-six symphony.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Velocity 4-Inch Direct Flow:\u003c\/strong\u003e Replaces the aging, narrow 3\" factory exhaust with a high-volume 4\" straight path, dropping pumping losses to zero and allowing your engine to breathe effortlessly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe Absolute Ultimate Cummins Roar:\u003c\/strong\u003e Unleashes that signature, raw 12V\/24V mechanical diesel sound.
