aFe BladeRunner Ported Ductile Iron Exhaust Manifold, Part Number 46-40154, for 2019–2024 Ram 1500 5.7L HEMI V8

These manifolds have both the inlet, and the outlet ports machined to match the factory gaskets. This allows for maximum flow, without compromising gasket performance. These manifolds have 25% Thicker walls than the crack-prone factory manifolds. The increase in thickness increases the rigidity of the manifolds and make them much more durable than the OE manifolds. These manifolds bolt directly to the factory y-pipe for an easy installation. BladeRunner Ported Ductile Iron Exhaust Manifold RAM 1500 (DT) 19-24 V8-5.7L HEMI

• Outflows the factory exhaust manifolds by 15%, improving performance and throttle response
• The machined ports match the factory gasket openings which maximizes exhaust flow
• Manifold mounting hardware is included for a hassle-free installation.
• 25% Thicker walls for increased rigidity and crack resistance
• Durable cast ductile iron construction

The aFe BladeRunner Ported Ductile Iron Exhaust Manifold is designed for 2019–2024 Ram 1500 models equipped with the 5.7L HEMI V8 engine. Part Number 46-40154 features precision-machined inlet and outlet ports that match the factory gasket openings, helping optimize exhaust flow while maintaining proper gasket sealing. The manifold is engineered to outflow the factory exhaust manifolds by up to 15 percent, supporting improved engine breathing, throttle response, and overall exhaust performance.

Compared with crack-prone original equipment manifolds, the aFe BladeRunner design uses walls that are 25 percent thicker for increased rigidity and improved resistance to cracking. Durable cast ductile iron construction provides dependable performance under demanding exhaust temperatures and operating conditions. The manifold bolts directly to the factory Y-pipe, allowing a straightforward installation using the included mounting hardware.

• Fitment: Designed for 2019–2024 Ram 1500 trucks with the 5.7L HEMI V8 engine; verify vehicle configuration before installation.
• Installation: Direct-fit replacement that attaches to the factory Y-pipe.
• Emissions: Not CARB approved; check local emissions regulations before purchase.
• Product Information: This product may carry a California Proposition 65 warning.

What's Included: One aFe BladeRunner ported ductile iron exhaust manifold and the required manifold mounting hardware. Installation should be performed with appropriate tools and service procedures.

Features:

• Improved Exhaust Flow: Outflows the factory exhaust manifolds by up to 15 percent to support improved performance and throttle response.
• Gasket-Matched Ports: Precision-machined inlet and outlet ports match the factory gasket openings for optimized flow and reliable gasket performance.
• Thicker, Crack-Resistant Walls: Walls are 25 percent thicker than the factory manifolds to increase rigidity and help resist cracking.
• Durable Direct-Fit Construction: Cast ductile iron construction bolts directly to the factory Y-pipe, with mounting hardware included for installation.
