These Hooker BlackHeart cast iron exhaust manifolds feature a 2.25-inch outlet and a natural cast finish, designed to sit close to the engine block for a wide range of replacement and engine-swap applications. The contoured design directs exhaust flow towards the exit port, enhancing performance. Made from durable cast iron, they ensure long-lasting, leak-free operation while reducing under-hood noise compared to traditional headers. Additionally, the shorty design allows for exhaust tubing to be routed closer to the frame or floor pan, maximizing ground clearance.
