PROFILE

ARM Motorsports' N63R/N63B downpipes for the 4.4L V8 Twin-Turbo powered G-Series allows you to take your BMW to the next level. Made with full 304 Stainless Steel and 3" construction these downpipes open up an incredible sound from the twin turbocharged V8 even with the stock exhaust!

CONSTRUCTION

As with all BMW's, everything is designed to fit in a very compact space, and the G-Series 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 N63R/N63B downpipes. The ARM G-Series downpipes use two O2 sensor bungs on each downpipe to allow for reinstalling the O2 sensors in their factory locations.
