{"product_id":"4-5-inch-stainless-steel-mandrel-bent-downpipe","title":"4.5-Inch Stainless Steel Mandrel-Bent Downpipe","description":"Featuring a 4.5-inch diameter and constructed from premium 304 stainless steel, this full mandrel-bent downpipe is designed for optimal exhaust gas flow.\n\nInstallation of this race downpipe leads to earlier power delivery and significantly improved turbo spool-up. The gradual transitions within the pipe allow exhaust gases to maintain their velocity, preventing a buildup of back pressure within the system and contributing to overall performance gains.\n\nThis product is explicitly designated for race, competition, or international use only. It is not intended for installation on vehicles registered for public road use within the United States. Sale on emissions-controlled vehicles within the United States requires a completed AMS Race Waiver form. International users should consult and adhere to their local laws and regulations regarding emissions and vehicle modifications.\n\nApplication is limited to 2020-2026 Toyota GR Supra models equipped with the B58 3.0L Turbo Engine, specifically for USDM models.","brand":"AMS Performance","offers":[{"title":"Default Title","offer_id":52686906753336,"sku":"AMS.38.05.0001-1","price":453.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/661658138.png?v=1784878263","url":"https:\/\/store.motormia.co\/products\/4-5-inch-stainless-steel-mandrel-bent-downpipe","provider":"MOTORMIA","version":"1.0","type":"link"}
