These Hooker 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. The Hooker LS cast iron exhaust manifolds are recommended for strong performance on engines up to 500 horsepower and are available in plain as cast finish. 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.

ALUMINUM: Most of the aluminum alloys used today contain some level of lead, usually less than .1%. Lead is known to the state of California to cause cancer and reproductive harm. Most aluminum alloys are physiologically inert in their solid form, and the lead is contained within, however user-generated dust and/or fumes may pose a hazard if inhaled or ingested. Heating beyond a certain temperature may also provide avenues for exposure.
STEEL (steel bolts): Steel is an iron alloy with several metals including Nickel and Chromium. Both Nickel and Chromium are known to the State of California to cause cancer and reproductive harm, respectfully. This warning applies to stainless steels as well.
