{"product_id":"mandrel-bent-stainless-steel-cat-back-exhaust-system-2","title":"Mandrel-Bent Stainless Steel Cat-Back Exhaust System","description":"The Milltek Sport Secondary Catalyst Bypass (SSXAU588) is engineered to remove the secondary catalytic converters, thereby improving exhaust gas flow and enhancing the vehicle's sound profile. Crafted from aerospace-grade Type 304, non-magnetic stainless steel, this bypass pipe is built for longevity and resistance to discoloration. The construction utilizes mandrel bends for consistent radius bends and optimized gas flow, with an enlarged bore diameter compared to stock components to maximize performance potential without sacrificing mid-range torque.\n\nIt is not required for Turbo-Back systems. Buyers should note that not all vehicles are equipped with secondary catalytic converters, and a visual check is recommended before ordering. The bypass pipe has a 3-inch (76.2mm) diameter and is not EC type-approved, meaning it is intended for off-road\/motorsport use only and will not pass a MOT test.\n\nSpecific fitment includes Audi RS3 Sportback (8V MQB – Pre Facelift Only) 2015-2017, RS3 Sportback 400PS (8V MQB – Facelift Only) Non-OPF\/GPF Models 2017-2018, RS3 Saloon\/Sedan 400PS (8V MQB) Non-OPF\/GPF Models 2017-2027, RS3 Saloon\/Sedan 400PS (8Y MQB EVO) Non-OPF\/GPF Models 2022-2027, and Audi TT Mk3 TTRS 2.5TFSI Quattro (Non-OPF\/GPF Models) 2016-2027.","brand":"Milltek Sport","offers":[{"title":"Default Title","offer_id":52689143660856,"sku":"SSXAU588","price":227.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687385090.jpg?v=1784902547","url":"https:\/\/store.motormia.co\/products\/mandrel-bent-stainless-steel-cat-back-exhaust-system-2","provider":"MOTORMIA","version":"1.0","type":"link"}
