From the material, exhaust headers 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\n\u003cp\u003eReplacing or upgrading your exhaust header is necessary for both engine performance and sound. Whether on or off the track, exhaust headers provide more horsepower and improved exhaust sound. FLASHARK offers many products to help you create your own custom engine headers. It's really easy and convenient to use: direct bolt-on, no modification needed. \u003c\/p\u003e","brand":"Flashark","offers":[{"title":"Default Title","offer_id":51637213593898,"sku":"FLES08036","price":169.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0293\/4423\/5619\/files\/2-11.jpg?v=1780623992","url":"https:\/\/flasharkracing.com\/products\/exhaust-header-for-2004-2005-chevrolet-impala-monte-carlo-l67-v6","provider":"Flashark","version":"1.0","type":"link"}
