Flowtech long tube headers are precision engineered using mandrel bent tubing, formed collectors and 5\/16\" flanges with sealing rings for a leak-free seal. All mounting hardware and gaskets are included for a simple installation. This header is coated in a high heat and corrosion resistant metallic ceramic thermal coating that increases exhaust velocity and reduces underhood temps for increased performance.\n\u003ch3\u003eFeatures:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFuel Economy From The Engine\u003c\/li\u003e\n\u003cli\u003eLeak Test For Max Performance\u003c\/li\u003e\n\u003cli\u003eCeramic Headers\u003c\/li\u003e\n\u003cli\u003eRust And Corrosion Resistance\u003c\/li\u003e\n\u003cli\u003eMandrel-Formed Power Plenum\u003c\/li\u003e\n\u003cli\u003eLeakproof O-Ringed Port Seals\u003c\/li\u003e\n\u003cli\u003eInclude All Mounting Hardware\u003c\/li\u003e\n\u003cli\u003eWorks with power steering and power brakes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eProduct Specifications:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Details:\u003c\/strong\u003e 1966-1974 Chevy\/GMC 1\/2 \u0026amp; 3\/4 \u0026amp; 1-Ton 2WD \u0026amp; 4WD, 1967-1974 Blazer\/Jimmy 2WD, 1966-1972 Blazer\/Jimmy K5\/Suburban 4WD, 1973-1974 Blazer\/Jimmy K5\/Suburban 2WD \u0026amp; 4WD: 283-400, Tube Size 1.5\", Collector Size 3\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAir Injection Tubes:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolt Size:\u003c\/strong\u003e 3\/8-16 x 3\/4 IN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolts Included:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCalifornia Proposition 65:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCARB (California) Compliant:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollector Attachment:\u003c\/strong\u003e 3-Bolt Flange\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollector Diameter:\u003c\/strong\u003e 3.00 IN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollector Port Diameter:\u003c\/strong\u003e 3.00 IN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollector Reducer Included:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollector Reducer Outlet Dia.:\u003c\/strong\u003e 2.50 IN\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 Long Tube\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive:\u003c\/strong\u003e 2WD, 4WD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEGT Port:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine:\u003c\/strong\u003e Chevrolet Small Block Gen I\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Ceramic Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlange Thickness:\u003c\/strong\u003e 0.3125 IN, 5\/16 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 II\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeader Style:\u003c\/strong\u003e Long Tube\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Mild Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Hardware Included:\u003c\/strong\u003e Yes\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 Oval\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Tubing Diameter:\u003c\/strong\u003e 1 1\/2 IN, 1.50 IN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Headers\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity:\u003c\/strong\u003e Sold as a Pair\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTube Wall Thickness:\u003c\/strong\u003e 16 GU\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eInstallation Notes:\u003c\/h3\u003e\n\u003cp\u003eRequires Flowtech air conditioning bracket 10042FLT. May require clutch linkage modification. Does not fit angle-plug heads. Do not use header wraps; they can cause header tube cracking from excessive heat or rust from moisture build-up and void the warranty. Breaking in an engine with ceramic-coated headers can damage the coating and void the warranty. Use cast-iron exhaust manifolds or old headers during engine break-in to prevent coating damage. Ceramic-coated headers require several heat cycles to fully cure before withstanding extreme heat.\nPlease call Flowtech Technical Service at 270-781-9741 for additional information regarding ceramic-coated exhaust products.\u003c\/p\u003e","brand":"Flowtech","offers":[{"title":"Default Title","offer_id":49707993301230,"sku":"BIG-31500FLT","price":531.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/9110\/6798\/files\/198194bb5d6d47abf7900748806adc3ec1be0df3.jpg?v=1791491544","url":"https:\/\/elmosspeedshop.com\/products\/flowtech-long-tube-header-ceramic-coated-31500flt","provider":"Elmo's Speed Shop","version":"1.0","type":"link"}
