{"product_id":"ppe-engineering-sc400-1-5-8-4-1-stainless-steel-headers","title":"PPE Engineering SC400 1-5\/8\" 4-1 Stainless Steel Headers","description":"The PPE Engineering 1140004-SS headers are a 4-1 design, crafted from 100% 304 stainless steel in the USA. They feature 1 5\/8″ runners that smoothly form into a 2.5″ collector outlet. These headers are engineered to deliver a significant power increase, with reported gains of 18-20 whp and 20+ ft-lb of torque.\n\nInstallation of these headers requires modification to your stock catalytic converters, or the use of high-flow catalytic converters or custom-made test pipes, as they are longer than the stock manifolds and not a direct fit. The product includes new outlet gaskets to aid in installation. For those seeking to reduce engine bay temperatures and maintain a clean appearance, an optional ceramic coating is available.\n\nMatching flanges for exhaust modification are also available at an additional charge. These headers are specifically designed for the Lexus SC400 models from 1991-2000.","brand":"XAT Racing","offers":[{"title":"Default Title","offer_id":52664140398904,"sku":"1140004-SS","price":1404.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687542360.webp?v=1784333959","url":"https:\/\/store.motormia.co\/products\/ppe-engineering-sc400-1-5-8-4-1-stainless-steel-headers","provider":"MOTORMIA","version":"1.0","type":"link"}
