{"product_id":"a350-4-2-1-header-system","title":"A350 4-2-1 Header System","description":"The Ace A350 Header represents the latest in exhaust performance for the FA20 and FA24 engines found in the GR86 and BRZ, as well as GT86 models. This 4-2-1 merge header is engineered to provide smoother airflow, leading to enhanced engine linear torque and the highest torque values among ACE Header products.\n\nConstructed entirely from #304 Stainless Steel and precisely TIG welded, this header is built for durability and performance. It features a 42.7mm runner that merges into a 50.8mm pipe, which then transitions to a 63mm pipe. The design includes a 20-degree converging angle and offers access for O2 sensors on either bank 1 or bank 2. The brushed finish is applied to help reduce surface temperature.\n\nIt is modular with the OEM front pipe back, meaning it can be directly matched up to original factory front pipes. The lightweight design contributes to an approximate total weight of only 6kg.\n\nIt is important to confirm if your vehicle is equipped with an Exhaust Temperature Sensor Bung prior to ordering, as an optional bung can be installed. This header is intended for daily driving applications.","brand":"Ace","offers":[{"title":"Default Title","offer_id":52686751367480,"sku":"NA421-425063-350","price":1870.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660671208.jpg?v=1784876307","url":"https:\/\/store.motormia.co\/products\/a350-4-2-1-header-system","provider":"MOTORMIA","version":"1.0","type":"link"}
