{"product_id":"bmw-s58-3-inch-304-stainless-steel-downpipes","title":"BMW S58 3-Inch 304 Stainless Steel Downpipes","description":"The CTS Turbo BMW S58 downpipes are a performance upgrade designed for competition use only and are not street legal. Constructed from durable 304 food-grade stainless steel, these downpipes feature a 3-inch (76mm) diameter and precisely laser-cut flanges for a secure fit. The design incorporates factory-like placement for O2 sensors, ensuring compatibility with diagnostic systems.\n\nEngineered with the latest 3D scanning technology and utilizing CAD software for exhaust flow simulation, these downpipes are optimized for seamless integration with both factory and CTS exhaust components. The primary benefit is enhanced exhaust flow, leading to faster spool, improved transient boost response, and the potential for higher boost levels, all while producing an aggressive sound that makes the S58 engine 'scream'.\n\nFor proper operation and to avoid illumination of the Check Engine Light (CEL), Stage 2 software tuning is strongly recommended. The use of Bootmod3 software is also highly recommended. These downpipes are compatible with the 2021+ BMW S58 M3\/M3 Competition, 2021+ BMW S58 M4\/M4 Competition, and 2023+ BMW S58 M2.\n\nNote: 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":52867526852920,"sku":"CTS-EXH-DP-0053","price":799.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687952153.webp?v=1787911676","url":"https:\/\/store.motormia.co\/products\/bmw-s58-3-inch-304-stainless-steel-downpipes","provider":"MOTORMIA","version":"1.0","type":"link"}
