We supply diesel aftermarket manifolds that are designed to improve your fuel efficiency. The manifolds are cast from high-quality blended steels for toughness and heat tolerance. Thicker exhaust flanges and center dividers provide greater strength and durability. The joints have tighter tolerances, 50% more surface contact, and are press fit to eliminate leakage. The smoother design allows even airflow to the turbo. High-temperature-resistant Ceramic Chrome coating adds an additional heat barrier to keep exhaust gas energy moving to your turbo to improve turbo response.
