The headers are constructed from heavy duty 16-gauge 409 stainless steel tubing for increased strength and durability.  These headers use a 10 in. long, 2.5 in. collector with 20 in. long primary tubes.  The 3\/8 in. thick header flange provides a leak-free seal and maximizes strength.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMandrel bent tubes provide consistent tubing diameters for better exhaust pulse flow and improved performance\u003c\/li\u003e\n\u003cli\u003e1-1\/2 in. and 1-5\/8 in. primary diameters available for increased exhaust flow and improved throttle response\u003c\/li\u003e\n\u003cli\u003eHeavy duty 16-gauge 409 Stainless Steel used for strength and durability\u003c\/li\u003e\n\u003cli\u003e10 in. long, 2.5 in. collector improves exhaust flow\u003c\/li\u003e\n\u003cli\u003e3\/8 in. thick header flange for a leak-free seal and maximum strength\u003c\/li\u003e\n\u003cli\u003eAvailable for both round and D-port exhaust ports\u003c\/li\u003e\n\u003cli\u003eHeader gaskets included\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAir Injection Tubes:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolts Included:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Flowtech Exhaust\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCARB (California) Compliant:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCatalytic Converter Quantity:\u003c\/strong\u003e 0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Exhaust\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollector Attachment:\u003c\/strong\u003e Weld-On\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollector Diameter:\u003c\/strong\u003e 2.50 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollector Length:\u003c\/strong\u003e 10.00 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollector Port Diameter:\u003c\/strong\u003e 2.50 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollector Reducer Included:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Silver\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDesign:\u003c\/strong\u003e Upright\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive:\u003c\/strong\u003e 2WD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEGT Port:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEmission Code:\u003c\/strong\u003e 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine:\u003c\/strong\u003e GM 90 Degree V6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Natural\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlange Thickness:\u003c\/strong\u003e 0.375 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGasket Or Seal Included:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade Type:\u003c\/strong\u003e Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeader Series:\u003c\/strong\u003e Flowtech\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeader Style:\u003c\/strong\u003e Upright\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstalled Height:\u003c\/strong\u003e 27.00 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 409 Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Hardware Included:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOxygen Sensor Port:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003epart type:\u003c\/strong\u003e Exhaust Header\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePort Shape:\u003c\/strong\u003e Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Tube Length:\u003c\/strong\u003e 20 inch in\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eWarranty:\u003c\/strong\u003e Manufacturer's Limited 90 Day Warranty\u003c\/p\u003e","brand":"FlowTech","offers":[{"title":"Default Title","offer_id":45520612229255,"sku":"FLT11585FLT","price":373.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0744\/4008\/1543\/files\/18e00ca98d0d5c6265c358cdd0019d9a.jpg?v=1788268770","url":"https:\/\/checkout.northernperformance.ca\/products\/flowtech-upright-headers-5","provider":"Northern Performance","version":"1.0","type":"link"}
