{"product_id":"3-inch-downpipe-with-catalytic-converters","title":"3-Inch Downpipe with Catalytic Converters","description":"The CTS Turbo downpipes are engineered to enhance the performance of the Mercedes-Benz W205 C63 and C63S models equipped with the M177 engine. These 3-inch downpipes replace restrictive factory catalytic converters and are designed for a bolt-on installation, requiring no welding and reusing OEM mounting points.\n\nConstructed from CAST T304 stainless steel and hand TIG welded with back-purging, these downpipes are built for durability and reliable performance. They feature 200-cell high-flow catalytic converters and OE-style heat shielding to manage under-hood temperatures, allowing for extended hard driving. The design aims to improve turbo spool, throttle response, and exhaust note, providing a louder and deeper tone.\n\nInstallation of these downpipes requires specific tuning, identified as Stage 2, to prevent a check engine light (CEL). The product is sold for competition use and is not legal for highway or street vehicles.","brand":"CTS Turbo","offers":[{"title":"Default Title","offer_id":52867526230328,"sku":"CTS-EXH-DP-0030-CAT","price":1399.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687951686.webp?v=1787911673","url":"https:\/\/store.motormia.co\/products\/3-inch-downpipe-with-catalytic-converters","provider":"MOTORMIA","version":"1.0","type":"link"}
