3" CATLESS DOWNPIPES 3" CATLESS DOWNPIPES Fits: BMW G30 M550I N63R Description 3" CATLESS DOWNPIPES N63R DOWNPIPE DESIGN As with all BMW's, everything is designed to fit in a very compact space, and the N63R M550i downpipes are no exception. 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 airflow smoother and installation easier. Consequently, the ARM N63R downpipes mount up to the turbos and midpipes with the same precision as you would expect from the factory M550i downpipes.
