{"product_id":"c4-corvette-5-7l-long-system","title":"C4 Corvette 5.7L Long System","description":"The American Racing Headers C4 Corvette Long System is specifically engineered for 1984-1991 C4 Corvettes equipped with the 5.7L V8 engine. This system is constructed entirely from 100% US-sourced 304 stainless steel, ensuring durability and resistance to corrosion. Key features include 3\/8\" thick laser-cut flanges for a reliable seal, hand-ported TIG welded inlets, and optimized primary tube routing for superior fit and performance. The system also incorporates merge collectors with scavenger spikes.\n\nThis long system comes with 1-3\/4\" primary tubes and a 3\" X-pipe. Customers have the option to choose between systems with high-flow catalytic converters (available with standard 300-cell or optional 400-cell G-Sport cats) or without cats.\n\nFor proper installation, all 84-91 C4 Corvettes will require an OEM GM LT1 Oil filter adapter; without this adapter, the systems will not fit. When ordering, customers must specify the exact model year, whether the vehicle has EGR, if it is a Coupe or Convertible, and if it has a Manual or Automatic transmission to ensure correct fitment. It is important to note that all ARH products are manufactured for racing purposes and their installation may affect the legal use of the vehicle on public roads.","brand":"American","offers":[{"title":"Default Title","offer_id":52686895153464,"sku":"C4-84134300LSWC","price":1890.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/662148378.jpg?v=1784878152","url":"https:\/\/store.motormia.co\/products\/c4-corvette-5-7l-long-system","provider":"MOTORMIA","version":"1.0","type":"link"}
