{"product_id":"tubolare-stainless-headers","title":"Tubolare Stainless Headers","description":"The Supersprint Tubolare stainless headers are a high-performance exhaust upgrade engineered to replace the restrictive, mass-produced stock exhaust manifolds on 2004-2010 BMW 545i and 550i E60 models. By utilizing a tubular design with precision merge collectors, these headers significantly reduce exhaust backpressure, allowing the N62 engine to operate more efficiently and realize substantial gains in both horsepower and torque. They are constructed from durable T304 stainless steel to ensure longevity and optimal flow characteristics.\n\nInstallation of this system requires careful planning regarding emissions compliance and hardware. This product is designed to connect specifically to Supersprint section 1 catalytic converters. Note that this component modifies or deletes factory emissions equipment; consequently, a signed waiver of emissions compliance is required for purchase. This item is not for sale or use in the state of California on any pollution-controlled vehicle as per the California Air Resources Board.\n\nDepending on your chosen configuration, certain setups may require professional installation or welding to integrate with existing stock catalytic converters. Please verify your specific model and submodel requirements before installation to ensure compatibility.","brand":"Supersprint","offers":[{"title":"Default Title","offer_id":52663916364088,"sku":"787901","price":3639.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687720238.jpg?v=1784330805","url":"https:\/\/store.motormia.co\/products\/tubolare-stainless-headers","provider":"MOTORMIA","version":"1.0","type":"link"}
