Show original supplier description
The Stainless Diesel T-4 24 Valve Exhaust Manifold is engineered to enhance performance for 1998.5-2002 Dodge Cummins trucks, particularly those used for sled pulling and high-power applications. Constructed with advanced shell molding technology, this manifold boasts a super-smooth interior and exterior casting for significantly improved flow over conventional sand-cast designs. The runners measure 1.650 inches internally, extending to the center outlet to facilitate high flow. The manifold features a robust 3/4 inch thick center section, allowing for custom porting, and thick walls designed to retain heat effectively. Installation of this manifold offers several performance benefits, including making large turbos more driveable, improving turbo spool-up by several hundred RPM, increasing horsepower, and widening the overall powerband. When installed with compatible modifications, it can also lead to increased fuel economy. The product is noted for its excellent fit and finish. This exhaust manifold is specifically designed for the 1998 - 2002 Dodge Ram 2500 and 1998 - 2002 Dodge Ram 3500 models equipped with the 24-valve Cummins engine.
