Aftermarket exhaust Manifolds

High-Quality Aftermarket Manifolds for Improved Performance

Big Rig Power offers a wide selection of high-quality aftermarket manifolds designed to improve the performance of your heavy-duty truck. Our aftermarket manifolds are cast from high-quality blended steels that provide toughness and heat tolerance, ensuring long-lasting durability. Thicker exhaust flanges and center dividers provide greater strength and durability, while tighter tolerances and press-fit joints eliminate leakage. The smoother design allows for even airflow to the turbo, increasing turbo response. Our aftermarket manifolds are also coated with a high-temperature resistant Ceramic Chrome coating that reduces heat and improves air velocity, resulting in lower manifold temperatures and EGT's.
