Description

These Flowtech cast iron exhaust manifolds with a 2.25 inch outlet and natural cast finish are designed to hug close to the engine block for a wide variety of replacement and engine-swap applications. They are cast from Hi-Silicon-Moly Ductile Iron for durability and corrosion resistance, providing years of leak-free performance with less under hood noise than traditional headers. The tight tuck design offers universal fit for most popular chassis and a clean traditional muscle car appearance.
