{"product_id":"3-5-high-flow-cat-downpipe","title":"3.5\" High-Flow CAT Downpipe","description":"The CTS Turbo 3.5″ High-Flow CAT Downpipe is engineered to replace the restrictive factory downpipe on Mercedes-Benz M133 engine vehicles, aiming to improve exhaust flow and unlock additional horsepower, particularly when the vehicle is tuned.\n\nConstructed from 3.5″ T304 stainless steel tubing, this downpipe features a 200cpi high-flow race catalytic converter to facilitate smooth exhaust gas exit. The construction includes 100% TIG welding with back purging for durability and integrity, an OE-style heat shield for protection, and a T304 stainless steel O2 bung. The manufacturer claims it provides a great sound with no drone, even when paired with the factory exhaust system, and offers perfect fitment for straightforward installation.\n\nThis downpipe is compatible with the 2013-2018 Mercedes A45 AMG Hatchback (W176), the 2013-2018 Mercedes CLA45 AMG Coupe (W176), and the 2014-2019 Mercedes GLA45 AMG SUV (X156), all equipped with the 2.0L 4cyl M133 engine. A crucial post-installation requirement is Stage 2 software, which is necessary to prevent a check engine light illumination.\n\nIt is important to note that this product is sold for competition use and is not legal for use in highway or street vehicles.","brand":"CTS Turbo","offers":[{"title":"Default Title","offer_id":52687533080888,"sku":"CTS-EXH-DP-0029","price":509.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/663677289.jpg?v=1784884964","url":"https:\/\/store.motormia.co\/products\/3-5-high-flow-cat-downpipe","provider":"MOTORMIA","version":"1.0","type":"link"}
