aFe BladeRunner Ported Ductile Iron Exhaust Manifold

2019–2024 Ram 1500 5.7L V8 HEMI

46-40154

Overview:

The aFe BladeRunner Ported Ductile Iron Exhaust Manifold is engineered specifically for the 2019 to 2024 Ram 1500 equipped with the 5.7L V8 HEMI engine. Designed to replace the factory exhaust manifolds, this high-performance component enhances exhaust flow and durability. It is ideal for Ram 1500 owners seeking improved throttle response and overall engine efficiency without compromising reliability or requiring extensive modifications.

By addressing common weaknesses found in OEM manifolds, the BladeRunner manifold offers a robust upgrade that supports both daily driving and spirited performance applications.

Key Features:

This exhaust manifold combines precision engineering with durable materials to deliver measurable improvements and long-lasting performance:

• Port-matched inlet and outlet openings precisely machined to factory gasket specifications for optimal exhaust flow and sealing.
• Outflows factory manifolds by approximately 15%, contributing to enhanced engine breathing and throttle response.
• Constructed with 25% thicker walls compared to OEM manifolds, significantly increasing rigidity and resistance to cracking.
• Durable cast ductile iron construction designed to withstand high temperatures and thermal cycling.
• Direct bolt-on fitment to the factory Y-pipe, ensuring a straightforward installation process without the need for modifications.
• Includes all necessary manifold mounting hardware for a hassle-free upgrade.

Construction & Design:

The BladeRunner manifold is crafted from premium ductile iron, a material known for its superior strength and thermal durability compared to standard cast iron. The 25% thicker wall design enhances structural integrity, reducing the risk of cracks that commonly affect factory manifolds under prolonged heat stress.

Precision port machining ensures that the inlet and outlet ports align perfectly with factory gaskets, maximizing exhaust gas flow while maintaining a reliable seal. This meticulous attention to detail helps maintain OEM-level fitment and gasket performance while improving overall exhaust efficiency.

Performance & Sound

By increasing exhaust flow by 15% over the stock manifolds, the aFe BladeRunner manifold helps reduce backpressure, allowing the 5.7L V8 HEMI engine to breathe more freely. This results in improved throttle response and can contribute to a more responsive driving experience. While primarily focused on performance and durability, the manifold’s design may also subtly enhance exhaust tone, delivering a cleaner and more aggressive sound characteristic of a well-tuned V8.

Installation & Fitment:

The manifold is designed for direct replacement of the factory exhaust manifolds on 2019–2024 Ram 1500 models with the 5.7L V8 HEMI engine. It bolts directly to the factory Y-pipe, requiring no additional modifications or custom fabrication. Installation is straightforward and supported by the included mounting hardware, making it accessible for professional installers and experienced enthusiasts alike.

What's Included:

• aFe BladeRunner Ported Ductile Iron Exhaust Manifold
