{"product_id":"4-1-stainless-steel-headers-1","title":"4-1 Stainless Steel Headers","description":"The PPE Engineering Lexus LS400 headers are a performance exhaust manifold system constructed from 100% 304 stainless steel, designed for specific vehicle applications. These headers feature a 4-1 design with 1 5\/8\" runners and a smooth formed collector with a 2.5\" outlet. The installation is a bolt-on process, and no O2 sensor extensions are required.\n\nThese headers are designed to provide a significant power increase, with reported gains of 18-20 wheel horsepower and 20+ ft-lb of torque. They are longer than stock manifolds and are not a direct fit to the stock catalytic converters. Modification of stock catalytic converters, the use of high-flow catalytic converters, or the creation of test pipes will be necessary for installation. New outlet gaskets are included, and matching flanges for exhaust modification are available separately.","brand":"PPE Engineering","offers":[{"title":"Default Title","offer_id":52664140431672,"sku":"1140005-SS","price":1595.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687542362.webp?v=1784333963","url":"https:\/\/store.motormia.co\/products\/4-1-stainless-steel-headers-1","provider":"MOTORMIA","version":"1.0","type":"link"}
