{"product_id":"sport-cat-back-exhaust-system-with-quad-gt-90-tips","title":"Sport Cat-Back Exhaust System with Quad GT-90 Tips","description":"The Milltek SSXAU644 is a resonated cat-back exhaust system engineered to enhance the sound and aesthetics of your vehicle while maintaining a responsible noise level. Designed as a direct replacement for the factory exhaust, this system requires no modifications for proper fitment and utilizes OEM hangers.\n\nConstructed from 2.50\" T304 anti-magnetic stainless steel, the SSXAU644 is built for longevity and resistance to harsh conditions and discoloration. The pipework, mufflers, and resonators are all made from this premium material. Mandrel bending ensures smooth, full-flow bends for improved exhaust gas flow, and an increased bore diameter contributes to optimal performance without sacrificing mid-range torque.\n\nThis cat-back system allows you to retain the use of your vehicle's factory exhaust valve system. The valved mufflers seamlessly integrate with the car's vacuum system, reusing the OE valves and operating as stock through the Drive Select options. The kit includes two post-cat downpipes, a center front silencer section, two valved rear mufflers, Quad GT-90 90mm polished tips, and all necessary installation hardware.\n\nThis exhaust system is specifically designed for Audi B9 S4 and S5 models with the 3.0T Quattro engine, excluding models with a factory rear sports differential. It is covered by a limited lifetime warranty for anti-corrosion and manufacturer defects.","brand":"Milltek","offers":[{"title":"Default Title","offer_id":52689135534392,"sku":"SSXAU644","price":2027.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687385483.jpg?v=1784902363","url":"https:\/\/store.motormia.co\/products\/sport-cat-back-exhaust-system-with-quad-gt-90-tips","provider":"MOTORMIA","version":"1.0","type":"link"}
