This is a brand new set of cast iron exhaust manifolds that 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.  These cast iron manifolds will provide 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. 
Intended for all GM LS (except LS7 and LS9) engine swap applications 
Recommended for strong performance on engines making up to 500 horsepower 
Tight tuck design provides universal fit for most popular chassis and a clean traditional muscle car appearance - ideal for GM E-Rod installations.
Free-flowing for good performance and catalytic converter efficiency.
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.
2.25-inch outlet diameter
When you pick these up for the first time, you will feel how truly heavy duty and well built these headers are.  A top quality upgrade for your LS application.  We have had good feedback so far for fitment on 1970-81 GM F-bodies, 82-88 GM G-bodies and 68-72 GM A-bodies with the LS engines.
