• These LS cast iron exhaust manifolds have been designed to hug close to the engine block so they fit into a wide variety of replacement engine swap applications.
• Their contoured design aims the exhaust directly at the exit port for greatly improved flow.
• They are cast from high silicon moly ductile iron to provide durability, leak free performance and less under the hood noise than conventional headers.
• They also feature 304 stainless steel mating flanges to help provide a leak-free installation, and a two bolt exit flange which can be used with OEM style gaskets and fasteners for an excellent seal.
