Description
aFe POWER BladeRunner Ported Ductile Iron Exhaust Manifolds
For Ram 1500 & Ram 1500 Classic 5.7L HEMI
The aFe POWER BladeRunner Ported Ductile Iron Exhaust Manifolds are engineered to solve one of the most common issues with factory exhaust manifolds—cracking caused by heat cycling and vibration—while delivering measurable performance gains. Designed for the 5.7L HEMI, these manifolds improve exhaust flow, throttle response, and long-term reliability compared to OE components.
Factory exhaust manifolds are prone to failure due to thin wall construction. BladeRunner manifolds feature 25% thicker walls than OE, significantly increasing rigidity and resistance to cracking, warping, and fatigue. This heavy-duty design ensures consistent performance even under high-heat and high-load conditions.
Improved Exhaust Flow & Performance
-
15% greater exhaust flow over factory manifolds
-
Improved throttle response and engine efficiency
-
Reduced exhaust restriction for better power delivery
The ported design helps the engine expel exhaust gases more efficiently, supporting improved overall performance.
Heavy-Duty Ductile Iron Construction
-
Constructed from high-strength cast ductile iron
-
25% thicker walls than factory manifolds
-
Superior resistance to heat cycling and vibration
-
Designed for long-term durability in demanding conditions
Precision Machined, Port-Matched Flanges
Both the inlet and outlet ports are CNC-machined to match factory gasket openings, ensuring:
-
Maximum exhaust flow
-
Proper gasket alignment and sealing
-
Long-term reliability without leaks
This precision machining allows increased airflow without compromising gasket performance.
Hassle-Free, Direct Bolt-On Installation
-
Direct bolt-on replacement for factory manifolds
-
Bolts directly to the factory Y-pipe
