However, BMW did an excellent job of engineering the downpipes to flow in the smoothest path from the turbocharges down to the mid pipe section. Our downpipes essentially followed the same exhaust flow path with a few small modifications to make installation easier. Consequently, the ARM N63 downpipes mount up to the turbos and midpipes with the same precision as you would expect from the factory 550i downpipes. \u003cbr\u003e\u003cbr\u003e\u003cimg style=\"float: none;\" alt=\"N63 Downpipes F10 550i Exhaust\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0082\/6687\/4995\/files\/Pic3_ee87fc49-af11-4026-a8c4-177db04de881.jpg?v=1593707438\" class=\"img-responsive\"\u003e\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e \u003cbr\u003e\u003cspan\u003eThe ARM N63 550i downpipes come with a \u003cstrong\u003eflex section to relieve stress\u003c\/strong\u003e between the upper and lower portion of the downpipe from engine movement during aggressive driving.
