From the material, \u003ca href=\"https:\/\/flasharkracing.com\/collections\/exhaust-header\"\u003ehigh-performance exhaust headers\u003c\/a\u003e are made of lighter, thinner steel, while exhaust manifolds are made of thick iron. Exhaust headers are also longer than exhaust manifolds. When in use, exhaust manifolds create back pressure, which lowers performance. Because each cylinder of the engine is given its own tube, however, headers eliminate this problem; thus, allowing the gases to exit without the creation of back pressure. Therefore, exhaust headers are a BETTER choice than an exhaust manifold.\u003c\/p\u003e","brand":"Flashark","offers":[{"title":"Default Title","offer_id":51797515600158,"sku":"FLES08253","price":194.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/7171\/1262\/files\/ExhaustHeaderfor1965-1975ChevroletChevyGMCBigBlock3964024274545026.5L6.6L7.4L_2.jpg?v=1777501195","url":"https:\/\/platinumhpsolutions.myshopify.com\/products\/1965-1975-big-block-chevy-headers-396-402-454","provider":"Platinum High Performance Solutions, LLC.","version":"1.0","type":"link"}
