Product Details
Hooker cast iron exhaust manifolds 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. Being cast iron means they will provide years of leak-free performance with less under hood noise than traditional headers. Plus, their shorty design means you can route exhaust tubing close to your frame/floor pan for maximum ground clearance. "Hook" up your GM LS engine with Hooker cast iron manifolds today!
Features:
- Intended for all GM LS (except LS7 and LS9) engine swap applications where durability, quiet operation, emissions compliance and leak-free sealing is desired
- Available in plain as-cast finish or with various Hooker ceramic coatings for reduced engine compartment temps and improved corrosion resistance
- 304 stainless steel mating flanges included (mating flange fasteners are not included)
- 2.25-inch outlet diameter
- 2 bolt exit flange configuration matches 2010 Camaro (also the same as the E-rod exhaust manifolds) which can be used with OE gaskets and fasteners if desired, for an OE quality seal
- Cast from Hi-Silicon-Moly Ductile Iron to provide durability and corrosion resistance
- Free-flowing for good performance and catalytic converter efficiency
- Tight tuck design provides universal fit for most popular chassis and a clean traditional muscle car appearance - ideal for GM E-Rod installations
