Product Description

The aFe 46-40164 is a BladeRunner ported ductile iron exhaust manifold engineered to replace the crack-prone factory manifold on 2009-2018 RAM 1500 and 2019-2024 RAM 1500 Classic trucks equipped with the 5.7L HEMI V8. Its ported inlet and outlet design is CNC machined to precisely match the factory gasket openings, delivering up to 15% more exhaust flow than the stock manifold without sacrificing seal integrity.

Built with 25% thicker walls than the OE casting, this manifold addresses one of the most common failure points on these trucks - factory manifold cracking from repeated heat cycling and vibration. The added material significantly increases rigidity and long-term durability, while the manifold still bolts directly to the factory Y-pipe for a straightforward installation without additional fabrication.

This manifold suits 5.7L HEMI RAM 1500 owners looking to replace a cracked or failing factory manifold with a more durable long-term solution, or anyone seeking a modest flow improvement as part of a broader exhaust upgrade - all while retaining full compatibility with the stock downstream exhaust system.
