{"product_id":"b9-audi-a4-2-0t-cat-back-exhaust-system","title":"B9 Audi A4 2.0T Cat-Back Exhaust System","description":"The CTS Turbo B9 Audi A4 2.0T cat-back exhaust system is crafted for performance enthusiasts, built from the ground up by CTS Turbo. Constructed from premium T304 stainless steel, this system features hand TIG welding and CNC mandrel-bent piping for optimal flow and durability.\n\nThis cat-back exhaust system boasts a 3″ diameter, non-resonated downpipe that transitions to dual 2.5″ exhaust pipes. It includes double-wall 4.0″ tips and drone-free resonators to provide an aggressive sound under hard acceleration while maintaining a subtle tone during cruising. The design is intended to replace the restrictive factory exhaust, offering a 10-12hp gain.\n\nKey product details include water jet cut flanges and the assurance that this system will not cause a Check Engine Light (CEL). It is compatible with the factory catalytic converter as well as aftermarket test-pipes and high-flow catalytic converters.\n\nFitment is specified for the 2017-2024 Audi A4 2.0T models, including facelift versions that may have fake exhaust tips integrated into the bumper (these tips will not be used). It also fits the 2017-2019 Audi AllRoad models.","brand":"CT","offers":[{"title":"Default Title","offer_id":52687556116792,"sku":"CTS-EXH-CB-0019","price":1019.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/664701666.webp?v=1784885070","url":"https:\/\/store.motormia.co\/products\/b9-audi-a4-2-0t-cat-back-exhaust-system","provider":"MOTORMIA","version":"1.0","type":"link"}
