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.\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e","brand":"Flashark","offers":[{"title":"Default Title","offer_id":40012745539683,"sku":"FLES08208","price":237.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0293\/4423\/5619\/products\/Exhaust-Header-for-1999-2004-Ford-F150-LOBO-5.4L-Flashark-1680072098.jpg?v=1680072099"},{"product_id":"exhaust-header-for-2006-2011-honda-civic-si-fg2-fa5","title":"Exhaust Header for 2006-2011 Honda Civic Si 8th Gen FG2\/FA5","description":"\u003cp\u003e\u003cstrong\u003eThanks to \u003ca href=\"https:\/\/www.youtube.com\/watch?v=IzAMvATOPtg\" title=\"Mailman Wins the First Race for Team FFR with the Help of FLASHARK!\"\u003e@flemingfamilyracing5752\u003c\/a\u003e for the support; shared by the winner;\u003c\/strong\u003e\u003c\/p\u003e\n\u003cdiv class=\"video-wrapper-col-2\"\u003e\u003ciframe width=\"560\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/IzAMvATOPtg?si=OHFx1ldF9hXNvBPi\" title=\"YouTube video player\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\n\u003ch3\u003e\u003cstrong\u003eFlashark Exhaust Headers for 2006-2011 Honda Civic Si 8th Gen FG2\/FA5\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eUpgrading or replacing the exhaust header is a key step in enhancing engine performance and sound for your 2006-2011 Honda Civic Si 8th Gen.

Exhaust headers are made from lighter, thinner steel, whereas exhaust manifolds are constructed from thick iron.

This results in improved performance, as the gases exit the engine more efficiently. For your 2006-2011 Honda Civic Si 8th Gen, upgrading to headers offers better performance by reducing back pressure and boosting horsepower and torque.

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":40012801179747,"sku":"FLES08221","price":109.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0293\/4423\/5619\/files\/Exhaust-Header-for-1997-1999-Jeep-Wrangler-TJ-2.5L-L4-Flashark-66234096.jpg?v=1697774686"},{"product_id":"exhaust-header-for-1994-2004-chevy-s10","title":"Exhaust Header for 1994-2004 Chevrolet S10丨GMC Sonoma 2.2L I4","description":"\u003ch3\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eBrand Name: FLASHARK\u003cbr\u003eCertificate: ISO9001:2000\u003cbr\u003eApplication: Automobile Exhaust Header\u003cbr\u003eMaterial: Stainless Steel\u003cbr\u003eSurface: Mirror Polish\u003cbr\u003eModel: EH28156\u003cbr\u003eInlet: 1.50\" \/ Outlet: 2.50\"\u003c\/p\u003e\n\u003cdiv style=\"text-align: left;\"\u003e\n\u003cimg alt=\"1994-2004 Chevy S10 GMC Sonoma 2.2L Headers Pipe Inner Diameter\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0293\/4423\/5619\/files\/ExhaustHeaderfor1994-2004ChevyS10GMCSonoma2.2LI4_2_480x480.jpg?v=1722826912\" style=\"margin-bottom: 16px; float: none;\"\u003e \u003cimg alt=\"1994-2004 Chevy S10 GMC Sonoma 2.2L Headers Outer Diameter\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0293\/4423\/5619\/files\/ExhaustHeaderfor1994-2004ChevyS10GMCSonoma2.2LI4_8_480x480.jpg?v=1722826913\" style=\"margin-bottom: 16px; float: none;\"\u003e\n\u003c\/div\u003e\n\u003ch3\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCNC Machined Flanges\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003ePolished 304 Stainless Steel\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eStandard Graphite Manifold Gaskets\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eDirect bolt on, no modification needed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eExhaust Header VS Manifold, which is the better choice? \u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/flasharkracing.com\/collections\/exhaust-header\"\u003eExhaust headers\u003c\/a\u003e offer better performance compared to traditional manifolds.

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.

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.

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. It'll increase high-flow air, and instantly gain 10 -15 Hp. \/ Tq. Whether on or off the track, exhaust headers provide more horsepower and improved exhaust sound.
