{"product_id":"super-competition-series-long-tube-headers","title":"Super Competition Series Long Tube Headers","description":"These long tube headers are crafted from durable 16-gauge mild steel and finished with a silver metallic ceramic coating for durability and heat resistance. The primary tubes measure 1-5\/8 inches in diameter and are 28 inches long, leading to a 3-inch diameter collector designed to reduce back pressure and increase power.\n\nThese headers are specifically designed for D-Port exhaust manifolds and are compatible with 350-455 cubic inch Pontiac engines. They are intended for use on 1970-1979 Pontiac Firebird and Trans Am models, as well as 1964-1975 Pontiac GTO, Le Mans, and Grand Am vehicles. For optimal performance and longevity, ceramic-coated headers require several heat cycles to fully cure, and it is recommended to use a cast-iron exhaust manifold as a heat sink during this process. Professional installation may be recommended for optimal fit and performance.","brand":"Hooker Headers","offers":[{"title":"Default Title","offer_id":52688734748984,"sku":"520-4901","price":399.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/664717959.jpg?v=1784894040","url":"https:\/\/store.motormia.co\/products\/super-competition-series-long-tube-headers","provider":"MOTORMIA","version":"1.0","type":"link"}
