{"product_id":"s63-4-4l-twin-turbo-downpipes","title":"S63 4.4L Twin-Turbo Downpipes","description":"The DTM-Tuning downpipes are engineered for optimal flow and a perfect fit on the BMW M5 F90 and M5 Competition F90, both equipped with the S63 4.4L twin-turbo engine. Construction features highest quality 2.0mm wall 304 stainless steel, with every joint being 100% TIG welded and back purged for maximum durability and performance. The design incorporates OEM-spec V-band flanges and all necessary brackets and mounts, ensuring a 100% bolt-on installation process.\n\nKey features of these downpipes include a significant power gain, faster spool-up, improved throttle response, and a reduction in under-hood temperature. They also contribute to increasing the lifespan of the turbos and add a desirable tone to the exhaust note. Each downpipe set comes with OE-style Heat Shielding, featuring a ceramic inner liner designed to reduce radiant heat by up to 70-80%, a thermal management feature inspired by racecar engineering.\n\nIncluded are Straight Tunable 02 Spacers with three inserts to help prevent check engine light conditions, especially when used with the Competition model without proper tuning. Customers can choose between optional GESI GEN2 400CPSI or ultra high-performance 200CPSI HJS HD catalytic converters, or a cat-delete option. The GESI converters are rated for 1000hp and are EPA Compliant, while the HJS HD converters are renowned for their quality, durability, and ability to meet strict Euro 6 emissions standards while providing flow close to straight pipes.\n\nCompatible vehicles include the BMW M5 Series F90 (2017-2023) and BMW M5 Competition Series F90 (2018-2023), both with the S63 4.4L V8 Twin Turbo engine. The product is backed by a limited lifetime warranty.","brand":"DTM-Tuning","offers":[{"title":"Default Title","offer_id":52687730147640,"sku":"RS.M5.F90.DP","price":2588.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/664704745.jpg?v=1784886566","url":"https:\/\/store.motormia.co\/products\/s63-4-4l-twin-turbo-downpipes","provider":"MOTORMIA","version":"1.0","type":"link"}
