{"product_id":"cat-back-exhaust-system-with-burnt-tips","title":"Cat-Back Exhaust System with Burnt Tips","description":"The Stillen 504452 cat-back exhaust system is engineered to replace restrictive factory components on the 2016-2024 Infiniti Q50 3.0T. By optimizing exhaust gas velocity and reducing backpressure, this system enhances both performance and sound. The configuration utilizes a 2.5-inch Y-pipe that connects to a 3-inch mid-pipe, which then branches into a dual rear exit setup featuring 4.5-inch bolt-on tips.\n\nBuilt for durability and fitment, the system uses 304 stainless steel construction and mandrel-bent tubing to ensure smooth flow. The mufflers are tuned to provide a mild, well-mannered note during cruising that transitions into an authoritative, aggressive tone under hard acceleration. The bolt-on design allows for adjustable tip positioning to accommodate various rear valance or diffuser configurations.\n\nThis system is backed by a limited lifetime warranty from the manufacturer, reflecting its construction quality and rigorous in-house testing at Stillen headquarters.","brand":"Stillen","offers":[{"title":"Default Title","offer_id":52664216584504,"sku":"504452","price":1632.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687390952.webp?v=1784335290","url":"https:\/\/store.motormia.co\/products\/cat-back-exhaust-system-with-burnt-tips","provider":"MOTORMIA","version":"1.0","type":"link"}
