{"product_id":"race-cat-back-exhaust-system-2","title":"Race Cat-Back Exhaust System","description":"The Milltek SSXAU376 is a cat-back exhaust system, specifically the Race Version with Quad Outlet Polished Tips, designed for enhanced performance and aesthetics. Constructed from aerospace-grade Type 304L stainless steel, this system ensures durability and resistance to discoloration. The 2.37-inch (60.30mm) diameter pipework is mandrel-bent for optimized gas flow, with enlarged bore diameters over stock to maximize performance without sacrificing mid-range torque.\n\nThis resonated system has undergone a comprehensive acoustic development process to produce a sporty and crisp exhaust note, while meticulously avoiding NVH, drone, or cabin resonance. The GT100 tip style adds a distinctive visual element. It is designed as a direct replacement for the factory exhaust, ensuring straightforward installation.\n\nCompatibility is specifically for the Audi B8.5 S4 3.0 Supercharged V6 (2012-2016) and the Audi B8.5 S5 3.0 TFSI Sportback (2012-2016). Note that the use of de-cats or sports cats (if applicable to other systems) is for off-road\/motorsport use only and would inhibit a vehicle from passing a MOT test; only EC type-approved components are legal for road use.","brand":"Milltek","offers":[{"title":"Default Title","offer_id":52689134813496,"sku":"SSXAU376","price":2938.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687764324.jpg?v=1784902346","url":"https:\/\/store.motormia.co\/products\/race-cat-back-exhaust-system-2","provider":"MOTORMIA","version":"1.0","type":"link"}
