{"product_id":"hooker-small-block-chevrolet-exhaust-manifolds-3","title":"Hooker 8527-3HKR - Small Block Chevrolet Exhaust Manifolds","description":"\u003cp\u003eHooker's new cast iron small-block Chevy exhaust manifolds offer an increase in performance and visual appearance over stock-style manifolds.  Their compact design fit into a wide variety of replacement and engine swap applications. This means you get the traditional look and easy fitment of a stock style exhaust manifold but now with a smoother, cleaner appearance, plus more modern features. These manifolds are cast out of high silicon-molybdenum ductile iron for high temperature strength and better resistance to oxidation and cracking. Internally these manifolds have a larger than stock 1 5\/8-inch cross-sectional area and 2 1\/2-inch outlets for better air flow and improved performance. Designed for raised D-port heads, these manifolds fit many popular GM applications including standard straight and Vortec straight plug head designs. Finishes include natural, silver, black, and titanium ceramic. Gaskets and hardware are included, along with weld-on flanges to aid in downpipe installation.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eA smoother, cleaner appearance compared to original exhaust manifolds, while maintaining a factory style look and feel\u003c\/li\u003e\n\u003cli\u003eMade from high silicon-molybdenum ductile iron for high temperature strength plus resistance to oxidation and cracking\u003c\/li\u003e\n\u003cli\u003eDesigned with a larger 1 5\/8” cross-sectional area and 2 ½” outlets for better air flow and increased performance\u003c\/li\u003e\n\u003cli\u003eDesigned for raised D-port heads\u003c\/li\u003e\n\u003cli\u003eAccommodates standard straight and Vortec straight plug head designs for better application coverage\u003c\/li\u003e\n\u003cli\u003eIncludes weld-on flanges for easier downpipe pipe installation (custom downpipe required)\u003c\/li\u003e\n\u003cli\u003eAvailable in natural cast iron or ceramic coated finishes (silver, black and titanium)\u003c\/li\u003e\n\u003cli\u003eIncludes mounting hardware and gaskets for inlet and outlet flanges\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolt size:\u003c\/strong\u003e 3\/8-16 x 3\/4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Hooker\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCARB (California) Compliant:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Exhaust\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollector Diameter:\u003c\/strong\u003e 2.50 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEmission Code:\u003c\/strong\u003e 3\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\u003eExhaust Port Shape:\u003c\/strong\u003e D-Port\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Ceramic Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeader Style:\u003c\/strong\u003e Manifold\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003epart type:\u003c\/strong\u003e Exhaust Manifold\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Tube Diameter:\u003c\/strong\u003e 1-5\/8 inch in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Manifold\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSub Category:\u003c\/strong\u003e Exhaust Manifolds\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eWarranty:\u003c\/strong\u003e Manufacturer's Limited 90 Day Warranty\u003c\/p\u003e","brand":"Hooker","offers":[{"title":"Default Title","offer_id":45520631660679,"sku":"HKR8527-3HKR","price":621.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0744\/4008\/1543\/files\/b7e095c7dbd0b6f42067813919b4e1b0.jpg?v=1788268702","url":"https:\/\/checkout.northernperformance.ca\/products\/hooker-small-block-chevrolet-exhaust-manifolds-3","provider":"Northern Performance","version":"1.0","type":"link"}
