{"product_id":"1uz-fe-4-1-stainless-steel-headers","title":"1UZ-FE 4-1 Stainless Steel Headers","description":"The PPE Engineering stainless steel headers are a 4-1 design featuring 1 5\/8\" runners and a smooth formed collector with a 2.5\" outlet. Constructed from 100% 304 stainless steel, these headers are designed for the Lexus LS400 model years 1998-2000. They come complete with new outlet gaskets.\n\nThese headers are not a direct fit to the stock catalytic converters and will require modification to your stock catalytic converters, the use of high-flow catalytic converters, or the fabrication of test pipes for proper fitment, as they are longer than the stock manifolds. Installation is a bolt-on process with no O2 sensor extensions required. The product is vehicle-specific.\n\nPower gains are estimated between 18-20 whp and 20+ ft-lb. Optional ceramic coating is available to help reduce engine bay temperatures and maintain the headers' appearance over time. Matching flanges for exhaust modification are also available at an additional charge.","brand":"PPE Engineering","offers":[{"title":"Default Title","offer_id":52686660436280,"sku":"1140005-SS","price":1436.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660176629.webp?v=1784875683","url":"https:\/\/store.motormia.co\/products\/1uz-fe-4-1-stainless-steel-headers","provider":"MOTORMIA","version":"1.0","type":"link"}
