{"product_id":"4-1-stainless-steel-headers-with-1-5-8-runners","title":"4-1 Stainless Steel Headers with 1 5\/8\" Runners","description":"The PPE Engineering Lexus GS430\/SC430 headers are engineered to enhance the exhaust system of your Lexus GS430 (2001-2005) and SC430 (2002-2005). This performance upgrade features a 4-1 header design, incorporating 1 5\/8\" diameter runners and a 2.5\" collector outlet for improved exhaust flow.\n\nConstructed from premium 100% 304 stainless steel, these headers are built for durability and corrosion resistance. They are designed as a direct fit to the factory catalytic converters, ensuring a straightforward installation process that does not require O2 sensor extensions. The package includes new outlet gaskets for a complete setup.\n\nThese headers are projected to deliver significant performance improvements, with an estimated gain of 18-20 wheel horsepower and over 20 ft-lb of torque. An optional ceramic coating is available, which helps reduce underhood temperatures and maintains the aesthetic appeal of the headers over time. The \"Vehicle Specific\" fitment specification ensures precise compatibility with the listed Lexus models.","brand":"PPE Engineering","offers":[{"title":"Default Title","offer_id":52663321788728,"sku":"1143003-SS","price":1596.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687527869.jpg?v=1784325933","url":"https:\/\/store.motormia.co\/products\/4-1-stainless-steel-headers-with-1-5-8-runners","provider":"MOTORMIA","version":"1.0","type":"link"}
