Do not compromise performance and sound with factory parts.\r\\n\r\\nDesigned using the latest in CAD technology; this part is made to fit perfectly in place of restrictive factory catalytic converter. Manufactured from CAST T304 stainless steel; hand TIG welded and back-purged to ensure years of reliable performance.\r\\n\r\\nIn addition to unleashing the power and performance of your 4.4 Twin Turbo, our High-Flow Cats will make your vehicle sound like it really should. When installed with factory exhaust it produces a louder and deeper growl with much more pronounced exhaust \"crackle\" on downshift. While up-shifting you will enjoy a confident \"punch!\" as you bang through all 8 gears. The sound will be even louder if you already have an aftermarket exhaust system.\r\\n\r\\n\u003cstrong\u003e\u003cu\u003eProduct Details:\u003c\/u\u003e\u003c\/strong\u003e\r\\n\u003cul\u003e\r\\n \t\u003cli\u003e80mm or 3.15\" diameter piping\u003c\/li\u003e\r\\n \t\u003cli\u003eCat size: 110mm OD x 90mm Long or 4.33\" OD x 3.54\" Long\u003c\/li\u003e\r\\n \t\u003cli\u003eIncludes 200 cell sport catalytic converter\u003c\/li\u003e\r\\n \t\u003cli\u003eDesigned and tested on a real car in the real world\u003c\/li\u003e\r\\n \t\u003cli\u003eCast T304 stainless steel, TIG welded back-purged construction\u003c\/li\u003e\r\\n \t\u003cli\u003eReplaces restrictive factory catalytic converter\u003c\/li\u003e\r\\n \t\u003cli\u003eGreat power upgrade with uncompromising performance\u003c\/li\u003e\r\\n \t\u003cli\u003eIncredible sporty exhaust sound, subtle when cruising\u003c\/li\u003e\r\\n \t\u003cli\u003eNo drone with factory exhaust\u003c\/li\u003e\r\\n\u003c\/ul\u003e\r\\n\u003cstrong\u003eFitment:\u003c\/strong\u003e\r\\n\u003cul\u003e\r\\n \t\u003cli\u003e2018-2021 F90 BMW M5 (Including Competition Models)\u003c\/li\u003e\r\\n \t\u003cli\u003e2020-2023 F91\/92\/93 M8 Coupe, Convertible \u0026amp; Gran Coupe (Including Competition Models)\u003c\/li\u003e\r\\n\u003c\/ul\u003e\r\\n \r\\n\r\\nTo remove the CEL that will occur, proper stage 2 tuning software must be used.","brand":"CTS Turbo","offers":[{"title":"Default Title","offer_id":48751998763294,"sku":"CTS-EXH-DP-0042-CAT","price":1199.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/pattersonperformanceparts.com\/products\/cts-turbo-bmw-f90-s63-m5-m5c-bmw-f91-92-93-m8-high-flow-cats-downpipe-set","provider":"Patterson Performance Parts","version":"1.0","type":"link"}
