{"product_id":"high-flow-cat-3-t304-stainless-steel","title":"High Flow Cat 3\" T304 Stainless Steel","description":"The CTS Turbo High Flow Cat is engineered as a direct replacement for the restrictive factory catalytic converter on B9 Audi A4, A5, Allroad, and Q5 vehicles equipped with 1.8T and 2.0T engines. Constructed from durable T304 stainless steel, this component features a fully tig-welded design for maximum strength and longevity. The 3-inch piping and a unique nearly 4-inch inlet flare that tapers to 3 inches are designed to optimize exhaust flow transitioning from the turbocharger.\n\nInstallation of this high-flow cat is intended to provide substantial power gains, improve overall exhaust flow, and produce a more aggressive, throaty exhaust note. It is positioned immediately after the turbocharger, and its design retains the exterior shape of a test pipe for a stealthier appearance. The product details include T304 stainless steel construction, a fully tig-welded design, a throaty sound, and potential for great power upgrades.\n\nTo mitigate potential Check Engine Lights (CEL) resulting from the catalytic converter change, proper tuning software is required; a Stage 2 software upgrade is strongly recommended. The specific fitment for this high-flow cat includes:\n\n*   2017 – 2019 Audi A4 1.8T\/2.0T\n*   2017 – 2019 Audi A5 1.8T\/2.0T\n*   2017 – 2019 Audi Allroad 1.8T\/2.0T\n*   2018 – 2020 Audi Q5 2.0T\n\nCrucially, this high-flow cat does NOT fit right-hand drive vehicles, GEN 3 ROW EA888.3 engines, or 2020+ models equipped with a V-band connection at the turbocharger. Additionally, it is confirmed to fit LHD vehicles and manual and automatic transmissions, but does NOT fit CVT transmissions.","brand":"CTS Turbo","offers":[{"title":"Default Title","offer_id":52687540060472,"sku":"CTS-EXH-TP-0006-CAT","price":269.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/663677366.webp?v=1784884988","url":"https:\/\/store.motormia.co\/products\/high-flow-cat-3-t304-stainless-steel","provider":"MOTORMIA","version":"1.0","type":"link"}
