{"product_id":"4-2-1-tubular-header-stainless-steel","title":"4-2-1 Tubular Header Stainless Steel","description":"The ISR Performance Tubular 4-2-1 Header is a performance exhaust manifold engineered for the Nissan 240sx models equipped with the KA24DE engine, covering model years 1991 through 1998. This header is constructed from durable stainless steel, featuring a 4-2-1 tube design aimed at optimizing exhaust flow and engine performance. Its 3-inch flange is expanded to ensure a straightforward bolt-on fitment with either the stock catalytic converter or various aftermarket test pipes and exhaust systems.\n\nIncluded with the header are essential components for installation: one exhaust manifold gasket, one 2-bolt 3-inch gasket, and the 4-2-1 tubular header itself. Users have reported positive experiences, noting good welds, quality construction, and perfect fitment. Some installation experiences suggest that adequate vehicle lift is necessary for proper access.\n\nIt is important to note that this product is legally intended for use only in competition vehicles that may never be registered, licensed, or used on public streets or highways, or for other exempted vehicles.","brand":"ISR Racing","offers":[{"title":"Default Title","offer_id":52688961044792,"sku":"IS-SSHD-240KA","price":365.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687906824.jpg?v=1784899369","url":"https:\/\/store.motormia.co\/products\/4-2-1-tubular-header-stainless-steel","provider":"MOTORMIA","version":"1.0","type":"link"}
