Overview:

The aFe BladeRunner Exhaust Manifold is a direct replacement designed specifically for the 5.9L Dodge Ram 2500 and Ram 3500 diesel trucks from 1998 to 2002. Engineered to solve the common cracking issues found in the factory exhaust manifold, this high-performance manifold offers superior durability and enhanced engine efficiency. Whether your OEM manifold is failing or you want to upgrade for improved performance, the BladeRunner manifold delivers longer life, reduced exhaust gas temperatures, and better throttle response.

Built to withstand the rigors of heavy-duty diesel applications, this manifold is ideal for diesel enthusiasts and professionals seeking reliable performance gains without compromising longevity.

Key Features:

The BladeRunner Exhaust Manifold combines advanced engineering and robust materials to provide significant improvements over the stock manifold. Key features include:

• Outflows the factory manifold by up to 50%, increasing exhaust efficiency
• Ported flanges ensure an excellent seal and a clean, professional appearance
• Thick wall design (0.25" vs. stock 0.15") enhances strength and prevents warping or cracking
• Merged runner design reduces exhaust backpressure for improved flow
• Dual 1/8" NPT exhaust gas temperature (EGT) probe ports allow precise monitoring on each bank
• Includes six port gaskets and all necessary mounting hardware for a complete installation
• Reinforcing rib along the flange adds structural integrity
• Machined ports provide a precise fit and smooth airflow

Construction & Design:

The BladeRunner manifold is cast from premium 304 stainless steel, offering superior corrosion resistance and strength compared to the factory ductile iron manifold. The thicker walls and reinforced flange design address the common cracking issues seen in stock manifolds, ensuring long-lasting durability under extreme operating conditions. The exhaust runners are carefully merged and ported to maximize flow efficiency, reducing exhaust gas temperatures and turbo lag.

Every detail, from the port machining to the inclusion of dual EGT ports, reflects a focus on performance and reliability tailored to the demanding needs of Dodge diesel trucks.

Performance & Sound

By increasing exhaust flow by as much as 23% over the stock manifold, the BladeRunner helps your turbo spool faster, resulting in quicker throttle response and improved overall engine performance. The reduction in exhaust gas temperatures also contributes to enhanced engine longevity and efficiency. While primarily focused on performance and durability, the manifold’s design supports a clean and efficient exhaust sound characteristic of a well-tuned diesel setup.
