Construction & Design

The manifold is crafted from high-silicon ductile iron, a material known for its exceptional strength and thermal resistance. This choice of material ensures the manifold can endure the intense heat cycles and vibrations generated by heavy-duty diesel engines without cracking or warping. The fully divided pulse design improves exhaust gas flow by separating exhaust pulses, which helps reduce backpressure and improves engine breathing.

Precision-engineered slip joints allow the manifold to expand and contract naturally with temperature changes, preventing stress buildup and reducing the risk of premature failure. This thoughtful design detail greatly enhances the durability and reliability of the manifold over the long term.
