AFE 46-40164 BladeRunner Ported Ductile Iron Exhaust Manifolds

The AFE 46-40164 BladeRunner Ported Ductile Iron Exhaust Manifolds will replace the cracked exhaust manifolds on your Dodge Ram 1500 5.7L Hemi. The factory exhaust manifolds are prone to cracking due to heat cycling. To provide superior strength and durability, these BladeRunner exhaust manifolds feature 25% thicker walls than the OE design. The added material helps withstand vibration and higher heat cycles without warping or cracking.

Machined Ports
These manifolds feature machined inlet and outlet ports to match the stock gaskets. This helps maximize flow without compromising gasket performance.

Trouble-Free Installation
These manifolds bolt directly to the OE Y-pipe for a straightforward installation.

Increased Wall Thickness
These manifolds feature walls that are 25% thicker than the crack-prone stock manifolds. The increase in thickness improves the rigidity of the manifolds and makes them much more durable than the factory manifolds.
