      Description

      Engine Swap Solution. The Flowtech LS Swap Exhaust Manifolds are designed to provide a reliable and efficient exhaust flow for GM LS engine swaps, allowing enthusiasts to install modern LS engines into classic vehicles while maintaining a clean and compact engine bay. Their design facilitates leak-free performance with reduced noise compared to traditional headers.

      Construction and Appearance. These manifolds feature cast iron construction using Hi-Silicon-Moly ductile iron for superior durability and corrosion resistance. They are finished with a silver ceramic coating that helps lower engine compartment temperatures and further protects against rust and wear, delivering both functionality and a traditional muscle car look.

      Installation. The manifolds are designed for straightforward installation with matching bolt patterns and included mating flanges. No drilling is required, and the tight tuck design ensures compatibility with most popular chassis, allowing for easy routing of exhaust tubing close to the frame for increased ground clearance.

      Application. These exhaust manifolds are designed for multi-fit usage and are compatible with GM Gen III and IV LS engines. They also fit the 79-04 Mustang among other popular chassis.
