Hooker Exhaust Manifolds

Hooker exhaust manifolds offer improved flow. They feature cast iron construction with 2.5 in. diameter outlets and have been designed to hug close to the engine block so they fit into a wide variety of replacement and engine-swap applications. Their contoured design aims the exhaust directly at the exit port for improved flow. Hooker exhaust manifolds will provide years of leak-free performance with less underhood noise than traditional headers. Plus, their shorty design means you can route exhaust tubing close to your frame/floor pan for maximum ground clearance.

Features include:

* Intended for engine swap applications where durability, quiet operation, and leak-free sealing is desired
* Available in plain as-cast finish or with various Hooker ceramic coatings for reduced engine compartment temperatures and improved corrosion resistance
* Nickel plated steel mating flanges, MLS mating flange gaskets, and mating flange hardware included
* Cast from high-silicon-moly ductile iron to provide durability and corrosion resistance
* 2.5 in. outlet diameter offers improved flow for maximum performance from a cast iron exhaust manifold
*Tight tuck design provides universal fit for most popular chassis and a clean, traditional muscle car appearance
