{"product_id":"b58-4-5-catless-downpipe","title":"B58 4.5\" Catless Downpipe","description":"The BimmerNetwork B58 True 4.5\" Catless Downpipe is engineered for enhanced exhaust flow and turbocharger performance in B58-equipped vehicles. This downpipe boasts a full 4.5-inch diameter that is maintained throughout its length, unlike other products that taper down shortly after the turbo outlet. This design minimizes exhaust restriction, reduces backpressure, and alleviates stress on the turbocharger, potentially leading to improved engine response and performance.\n\nFor those seeking a custom exhaust setup, it can be cut at the taper and welded to a larger diameter flex joint. The product is explicitly for off-road use only, with a disclaimer stating that installation on a motor vehicle is illegal in most states and that BimmerNetwork does not sell for road use.\n\nThis downpipe is compatible with all Bmw\/Toyota B58-equipped models, specifically covering Gen 1 and Gen 2 B58 engines, including the Toyota Supra MK5. Fitment spans from 2016-2019 models such as the M140i, M240i, 340i, 440i, 540i, 640i GT, and 740i. It also fits 2019-2020 models like the Z4 M40i and GR Supra 3.0. The compatibility extends to 2020-Present models across various BMW series including the 3 Series (M340i), 4 Series (M440i), 5 Series (540i LCI), 6 Series GT (640i GT), X5 (xDrive40i, sDrive40i), X6 (xDrive40i, sDrive40i), X7 (xDrive40i), 7 Series (740i LCI), 8 Series (840i), and the 2 Series (M240i), as well as the 2021+ Toyota Supra 3.0 and Z4 M40i.","brand":"Bimmer Network","offers":[{"title":"Default Title","offer_id":52687127019832,"sku":"BNDPB58","price":299.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/662153402.webp?v=1784880628","url":"https:\/\/store.motormia.co\/products\/b58-4-5-catless-downpipe","provider":"MOTORMIA","version":"1.0","type":"link"}
