{"product_id":"vr30ddtt-street-full-downpipes","title":"VR30DDTT Street Full Downpipes","description":"The AMS Performance VR30DDTT Street Full Downpipes offer a full 3-inch mandrel-bent stainless steel construction designed for maximum performance and durability. These downpipes integrate GESI catalytic converters, providing an emissions-conscious solution for competition vehicles. The long, gradual transitions within the mandrel-bent piping maintain exhaust gas velocity, preventing back pressure buildup and contributing to improved turbo spool-up and power delivery.\n\nDuring testing on an AMS shop Q60 equipped with these downpipes and an Red Alpha Tune, significant gains of 20 horsepower were observed over lower downpipe configurations, with no Check Engine Lights (CELs) reported. The power delivery was noted to come on earlier, and the twin turbos exhibited significantly improved spool-up.\n\nIt is crucial to note that this product is designated for race-only vehicles, defined as those used exclusively for competition and not legal for registration on public roads within the United States. Sale on emissions-controlled vehicles within the U.S. requires a completed AMS Race Waiver form. International users must adhere to their local regulations.","brand":"AMS Performance","offers":[{"title":"Default Title","offer_id":52872080523576,"sku":"AMS.28.05.0002-1","price":849.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/vr30ddtt-street-full-downpipes","provider":"MOTORMIA","version":"1.0","type":"link"}
