{"product_id":"jdm-racing-spec-exhaust-header","title":"JDM Racing Spec. Exhaust Header","description":"The FLASHARK exhaust header is engineered to enhance the performance of your 2001-2005 Lexus IS300 with the 3.0L 2JZ-GE DOHC engine. Its 2 x 3-1 JDM racing spec. design aims to significantly reduce exhaust back pressure and maximize exhaust airflow.\n\nThe package includes the exhaust header, three premium metal gaskets, and three nuts, providing everything required for installation. An O2 sensor bung is integrated, and a metal gasket is included, allowing for the use of factory oxygen sensors. However, due to its catless design, it is recommended to use O2 sensor spacers (defoulers) to prevent a Check Engine Light (CEL).\n\nThis header is compatible with the 3.0L 2JZ-GE DOHC Inline-6 Engine, Chassis Code XE10, and is also known as the Toyota Altezza. While not explicitly stated as long tube headers, the design functions similarly by replacing the factory manifold and upper catalytic converter sections to unlock mid-range torque and top-end horsepower.\n\nUsers can expect potential horsepower and torque gains of 10 to 15 HP\/TQ, along with an improvement in engine efficiency that may lead to a 0.5 MPG increase in fuel economy. The header will also contribute to a deeper, throatier, and louder racing exhaust tone, especially under acceleration. It is important to note that this is a catless header, generally recommended for off-road or track use.","brand":"SAMexhaust","offers":[{"title":"Default Title","offer_id":52689382375736,"sku":"FLES08222","price":149.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687663025.jpg?v=1784906020","url":"https:\/\/store.motormia.co\/products\/jdm-racing-spec-exhaust-header","provider":"MOTORMIA","version":"1.0","type":"link"}
