aFe Power BladeRunner Ductile Iron Exhaust Manifold for 1998.5-2002 Dodge Ram 5.9L Cummins 24V, Part Number 46-40032

Eliminate the costly exhaust manifold cracks prevalent in the factory exhaust manifold. The aFe BladeRunner exhaust manifold for the popular 98.5-02 5.9L Dodge Ram Cummins (24V) sets a new standard. In recent testing, this exhaust manifold outflowed the factory exhaust manifold by 50% improving performance and throttle response. The thick wall (0.25in. vs. 0.15in.) design increases strength eliminating warping and cracking. The matched ports and a merged runner design reduces exhaust backpressure, maximizing exhaust flow. Once you install this awesome exhaust manifold, you will feel improved turbo spool up times, improved throttle response and increased performance.

The aFe Power BladeRunner Ductile Iron Exhaust Manifold, Part Number 46-40032, is a durable stock-replacement upgrade for 1998.5-2002 Dodge Ram trucks equipped with the 5.9L Cummins 24-valve diesel engine. Designed to address the cracking and warping commonly associated with the factory manifold, this ductile iron assembly uses a heavy-wall construction to provide improved strength and long-term reliability under demanding exhaust temperatures.

In testing, the aFe Power BladeRunner manifold outflowed the factory exhaust manifold by up to 50 percent, helping reduce exhaust backpressure and improve turbocharger spool-up, throttle response, and overall engine performance. Machined ports and a merged runner design promote smoother, more efficient exhaust flow, while the cast ductile iron construction provides a reliable foundation for street, towing, and performance applications. Two 1/8-inch NPT exhaust gas temperature ports are included for gauge installation and monitoring.

Designed as a direct-fit replacement for applicable Dodge Ram diesel trucks, the aFe Power BladeRunner Exhaust Manifold fits 1998, 1999, 2000, 2001, and 2002 Dodge Ram 2500 and Ram 3500 models with the L6 5.9L Cummins engine, including 1998.5 applications. This emissions-compliant automotive component carries California Air Resources Board Executive Order D-550-39 where applicable. Professional installation is recommended, and all related hardware and vehicle-specific installation requirements should be verified before installation.

Features:

• Thick-Wall Ductile Iron Construction: Provides increased strength and resistance to warping and cracking compared with the thinner factory manifold design.
• High-Flow Port and Runner Design: Machined ports and merged runners reduce exhaust backpressure and promote efficient exhaust flow.
• Improved Turbocharger Response: Helps support faster turbo spool-up, sharper throttle response, and improved engine performance.
• Integrated Exhaust Gas Temperature Ports: Includes dual 1/8-inch NPT ports for installing exhaust gas temperature gauges.
