{"product_id":"flowtech-ls-swap-exhaust-manifolds-natural-cast-finish-11730flt","title":"Flowtech LS Swap Exhaust Manifolds - Natural Cast Finish - 11730FLT","description":"These Flowtech cast iron exhaust manifolds have a 2.25-inch outlet, natural cast finish, and are designed to hug close to the engine block so they fit into a wide variety of replacement and engine-swap applications at a budget-friendly price. 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.\n\u003ch3\u003eFeatures:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eIntended for GM LS engine swap applications where durability and leak-free sealing is desired at a budget-oriented price\u003c\/li\u003e\n\u003cli\u003eNickel plated steel mating flanges included (mating flange fasteners are not included)\u003c\/li\u003e\n\u003cli\u003e2.25 inch outlet diameter offers improved flow for maximum performance from a cast iron exhaust manifold\u003c\/li\u003e\n\u003cli\u003e2 bolt exit flange configuration matches the E-rod exhaust manifolds for a factory like fitment.
