{"product_id":"long-tube-exhaust-headers-4","title":"Long Tube Exhaust Headers","description":"The Flowtech 31150FLT long tube exhaust headers are engineered to provide a perfect combination of performance and value for specific Oldsmobile V8 applications. Precision-crafted with mandrel-bent tubing and formed collectors, these headers ensure consistent exhaust flow. The 5\/16-inch thick flanges are equipped with sealing rings, guaranteeing a leak-free seal and maximizing performance.\n\nConstructed from durable mild steel, the headers are finished with a silver metallic ceramic thermal coating. This advanced coating not only resists high heat and corrosion but also increases exhaust velocity and reduces underhood temperatures, contributing to enhanced performance. The package includes all necessary mounting hardware and gaskets for a straightforward installation.\n\nThese headers are designed to fit 1968-1974 Oldsmobile Cutlass models (excluding Supreme) and 442 models equipped with 350-403ci engines. They feature 1.75-inch primary tubes that lead to a 3-inch collector. A collector reducer is included, allowing for a 2.50-inch outlet diameter. Please note that these headers are not CARB compliant and do not include air injection tubes or an O2 sensor port.","brand":"Flowtech","offers":[{"title":"Default Title","offer_id":52688384491832,"sku":"FTC-31150FLT","price":572.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/662660881.webp?v=1784889406","url":"https:\/\/store.motormia.co\/products\/long-tube-exhaust-headers-4","provider":"MOTORMIA","version":"1.0","type":"link"}
