aFe BladeRunner Exhaust Manifold
2019–2024 Ram 1500 5.7L V8 HEMI
Part #: 46-40154
Overview
The aFe BladeRunner Ported Ductile Iron Exhaust Manifold is a precision-engineered upgrade designed specifically for the 2019 to 2024 Ram 1500 equipped with the 5.7L V8 HEMI engine. This direct-fit manifold replaces the factory exhaust manifolds to improve exhaust flow, enhance throttle response, and increase overall engine efficiency without sacrificing reliability. It is an ideal solution for Ram 1500 owners seeking a durable, high-performance exhaust component that supports both daily driving and spirited performance applications.
By addressing common weaknesses found in OEM manifolds, the BladeRunner manifold offers a robust and long-lasting upgrade that withstands high temperatures and thermal cycling, ensuring consistent performance under demanding conditions.
Key Features
The aFe BladeRunner manifold combines advanced engineering with durable materials to deliver measurable performance improvements and enhanced longevity:
- 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 improved 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 repeated 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. This robust construction helps prevent common issues such as cracking and warping that can occur with prolonged exposure to high exhaust temperatures.
Its 25% thicker wall design enhances structural integrity, providing a more rigid and reliable manifold that maintains performance over time. Precision port machining ensures perfect alignment with factory gaskets, maximizing exhaust gas flow while maintaining a reliable seal and OEM-level fitment.
Performance & Sound
By increasing exhaust flow by approximately 15% over stock manifolds, the aFe BladeRunner manifold reduces backpressure, allowing the 5.7L V8 HEMI engine to breathe more freely. This improvement results in enhanced throttle response and a more responsive driving experience. While primarily focused on performance and durability, the manifold’s design may also subtly enhance the exhaust tone, delivering a cleaner and more aggressive sound characteristic of a well-tuned V8 engine.
Installation & Fitment
This manifold is designed as a direct replacement for the factory exhaust manifolds on 2019–2024 Ram 1500 models equipped with the 5.7L V8 HEMI engine. It bolts directly to the factory Y-pipe without requiring any additional modifications or custom fabrication. Installation is straightforward and supported by the included mounting hardware, making it accessible for both professional installers and experienced enthusiasts.
