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\/N63TU downpipes mount up to the turbos and midpipes with the same precision as you would expect from the factory 550i downpipes. \u003c\/span\u003e\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\/Pic2_7fbed789-fb1d-4c35-bcb4-a64a083c90d1.jpg?v=1593707440\" class=\"img-responsive\"\u003e\u003cbr\u003e \u003cbr\u003e\u003cspan\u003eThe ARM N63\/N63TU 550i downpipes come with a flex section to relieve stress between the upper and lower portion of the downpipe from engine movement during aggressive driving. To further reduce any tension on the turbochargers, we have developed an upper and lower bracket, one being on the section of pipe above the flex joint where it secures to the engine block, and the other on the lower portion below the flex joint where it is secured to the transmission housing. These are the same points BMW designed their factory 550i downpipes to be secured, which means a strong and lasting connection safe for all the components on the vehicle.\u003c\/span\u003e\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\u003cbr\u003e \u003cbr\u003e\u003cspan\u003eThe ARM N63\/N63TU 550i Downpipes utilize two O2 sensor bungs on each downpipe to allow for reinstalling the O2 sensors in their factory locations.
