{"product_id":"high-flow-cat-3-5-inch-flange-3-inch-tubing","title":"High Flow Cat, 3.5-Inch Flange, 3-Inch Tubing","description":"The CTS Turbo High Flow CAT is a performance-oriented downpipe engineered specifically for the EVO4 AWD (4-motion or Quattro) platform, fitting the MK8 VW Golf R and 8Y Audi S3. It replaces the restrictive factory downpipe, which can hinder horsepower gains, particularly when the vehicle is tuned. This high-flow catalytic converter is constructed from 3.5-inch cast stainless steel and features mandrel-bent 3-inch stainless steel tubing for smooth exhaust gas flow.\n\nKey features include a 100% TIG-welded construction for durability and a cast stainless steel downpipe flange for a secure fit. It also includes a removable reducer to adapt to the factory exhaust system and utilizes factory mounting locations for easier installation. The design aims to provide enhanced performance and sound without introducing drone, even with the factory exhaust system.\n\nThis downpipe is designed for the 2022 and newer VW MK8 Golf R and 2022 and newer Audi 8Y Audi S3. However, it is explicitly noted that this part is not compatible with OPF\/GPF equipped vehicles. Additionally, the product description mentions that most 2022+ vehicles have updated 'tamper-proof' downpipe hangers, and users may need to purchase an old-style hanger (part number 1K0253144AE) from an OEM parts retailer for easier removal. A California Proposition 65 warning is also included regarding cancer and reproductive harm.","brand":"CTS","offers":[{"title":"Default Title","offer_id":52687561883960,"sku":"CTS-EXH-DP-0056-CAT","price":539.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687894873.webp?v=1784885109","url":"https:\/\/store.motormia.co\/products\/high-flow-cat-3-5-inch-flange-3-inch-tubing","provider":"MOTORMIA","version":"1.0","type":"link"}
