Exhaust Manifolds – Cast Iron & Exhaust Gas Manifolds
Process: Green Sand Casting / or Investment Casting
Material:Grey Iron | Ductile Iron | Cast Steel
Exhaust Manifolds: OEM Standard & Strictly Inspection
Leesh specialize in OEM exhaust manifolds production, adhering to strict industry standards to match the fit and function of original equipment. Each exhaust manifold is manufactured with high-grade materials, ensuring compatibility with both gasoline and diesel engines.
Our manifold exhaust designs prioritize optimal exhaust flow, reducing backpressure to enhance engine efficiency and performance. Whether you need a direct replacement or an upgrade, our manifolds meet the highest quality benchmarks.
Our product line includes cast iron exhaust manifolds options, known for their exceptional heat resistance and longevity. These robust manifolds are ideal for heavy-duty applications, standing up to the harshest operating conditions.
We also offer exhaust gas manifold variants, designed to efficiently collect and channel exhaust gases from engine cylinders to the exhaust system. Each manifold features a precision-machined exhaust collector manifold, ensuring seamless integration with your engine’s exhaust setup.
