The LS swap market continues to be insanely popular but with all of its innovations, there lacks a budget friendly option for exhaust systems. While stainless long tubes are nice, they can put a nice dent in your wallet and are traditionally available for a limited number of applications. That's why Holley is pleased to introduce Flowtech's new line of LS swap exhaust manifolds. These block hugger style cast iron manifolds are designed to fit tightly around your GM LS motor and maximize space in tight engine bays. These entry level manifolds are sure to be a great alternative to modifying factory OE units.


Flowtech's cast iron exhaust manifolds have a 2.25 inch outlet, and are designed to hug close to the engine block. This allows them to fit into a wide variety of replacement and engine-swap applications at a budget friendly price. Their cast iron construction will provide years of leak-free performance with less under hood noise than traditional headers. Also, their shorty design means you can route exhaust tubing close to your frame and/or floor pan for maximum ground clearance. With three finishes available (including natural cast, black ceramic and silver ceramic) Flowtech's cast iron manifolds will uphold to weathering and provide lasting looks when compared to traditional mild steel headers.
