PROFILE

ARM Motorsports new N63/N63TU Catted Downpipes for the 4.4L V8 Twin-Turbo powered 550i allows you to take your N63/N63TU engine to the next level. Designed with the same precision as our N63 Catless Downpipes, the ARM N63 Catted Downpipes feature high-flow 200 cell ceramic sport catalytic converters positioned in the OEM location.

DYNO PROVEN

Tested on an N63-powered 2012 550i GT xDrive with a Stage 2 tune, the addition of ARM’s 3" Downpipes and Cold Air Intake yielded +48whp and +43wtq, raising output to 460awhp and 525awtq.

CONSTRUCTION

Like all BMW performance components, precision fitment is critical. The ARM N63 Catted Downpipes are engineered to follow the smoothest possible exhaust flow path while easing installation. 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.

IN THE BOX

• 2x ARM N63 3" Catted Downpipes
• 2x ARM Crush Brackets
• 1x Hardware Kit

FITMENT GUIDE

The ARM N63/TU Catless Downpipes are compatible with the cars on the list below that have a slip-fit style OEM downpipe only. The most reliable and accurate way is to simply look under your vehicle for the connection point between the downpipe and mid pipe. In most cases, this is visible without having to remove any undertrays or covers. If your connections look like the images below and your car is listed on the fitment chart, these will fit your vehicle.
