{"product_id":"4-1-headers","title":"4-1 Headers","description":"The Supersprint 4-1 headers are equal-length primary exhaust headers engineered to optimize engine airflow and power output. By replacing the restrictive factory pre-catalytic converter, these headers reduce exhaust backpressure, allowing the engine to breathe more efficiently throughout the power band.\n\nThis system is designed as a performance-oriented upgrade and requires proper installation to maintain exhaust system integrity. As a header component replacing a pre-catalytic converter, users should verify local emission regulations regarding the removal or replacement of factory emissions hardware. These headers are specifically tailored for the 2013 Scion FR-S 2.0i, providing a direct fit that leverages Supersprint's long-standing research and development in exhaust manifold design.","brand":"Supersprint","offers":[{"title":"Default Title","offer_id":52866419163448,"sku":"891201","price":3029.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687703013.webp?v=1787907531","url":"https:\/\/store.motormia.co\/products\/4-1-headers","provider":"MOTORMIA","version":"1.0","type":"link"}
