LS ENGINE SWAP CAST EXHAUST MANIFOLDS; BLACK-MAXX BLACK CERAMIC COATED- Clearance (LAST ONE!)


While Hedman Hedders has thoughtfully designed application specific headers that fit right into many of the world's most popular Classic American Muscle Cars, the shear variety of vehicles LS engines find their way into makes it impossible to economically offer a specific design for everything. In response to the demand for an LS header that will work for some of these less popular LS swap projects, Hedman Hedders offers an LS Engine Swap Cast manifold Set that fits tight against the engine block for maximum clearance and compatibility-- But larger, smoother exhaust runners and ports that blow factory manifolds away. These compact LS manifolds are super durable, and compact to improve the chances these will fit right into your special project's engine room. This set of LS swap cast manifolds has Hedman's BLACK-MAXX Satin Black Ceramic-Metallic coating that offers thermal protection up to 1400F and wards off corrosion.
