PROFILE

ARM Motorsports' N63R downpipes for the 4.4L V8 Twin-Turbo powered M550i allows you to take your N63R engine to the next level. This increase in exhaust flow allows for the turbos to spool faster, increasing power and torque throughout the RPM range of your M550i.

CONSTRUCTION

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 turbochargers down to the mid pipe section. 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. The ARM N63R M550i downpipes come with a mesh flex section to relieve stress between the upper and lower portion of the downpipe. The ARM N63R M550i downpipes use two O2 sensor bungs on each downpipe to allow for reinstalling the O2 sensors in their factory locations.
