ARM Motorsports new N63 Downpipes with the 2-Bolt midpipe flange for the 4.4L V8 Twin-Turbo powered 550i allows you to take your N63 engine to the next level. Made with full 304 Stainless Steel and 3" construction these downpipes provide a significant increase in power and torque over the OEM catted downpipes. In addition to the massive power gains, these downpipes open up an incredible exhaust sound from the turbocharged V8 that will shock and awe onlookers!

By replacing the OEM downpipes with the ARM Catless Downpipes, you'll be removing the restriction from the OEM converters which will reduce exhaust back-pressure and allow the exhaust from the turbochargers to flow more freely. This increase in exhaust flow allows for the turbos to spool faster, increasing power and torque throughout the RPM range of your 550i.
DYNO PROVEN
Our test car was an N63-equipped 2012 550i GT optioned with the all-wheel drive xDrive system. It came with a Stage 2 tune installed making our baseline numbers 412awhp and 482awtq. After installing the ARM 3" Downpipes and Cold Air Intake, we recorded gains of 48whp and 43wtq over the standard Stage 2 tune for an impressive total of 460awhp and 525awtq.CONSTRUCTION
As with all BMW's, everything is designed to fit in a very compact space, and the N63 550i 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 installation easier. Consequently, the ARM N63 downpipes mount up to the turbos and midpipes with the same precision as you would expect from the factory 550i downpipes.The ARM N63 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 a lower bracket, on the lower portion below the flex joint where it is secured to the transmission housing via a crush bracket.
The ARM N63 550i Downpipes utilize two O2 sensor bungs on each downpipe to allow for reinstalling the O2 sensors in their factory locations. This not only allows for the accommodation of the factory upper heat shield, but also allows the correct O2 sensor data to be sent to the DME. This is essential for the DME to properly monitor the parameters in the exhaust that are critical to having your 550i motor running smoothly.

FITMENT GUIDE
The ARM N63 Catless Downpipes are compatible with the cars on the list below that have a 2-Bolt 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. | Make | Chassis | Model | Engine |

Haru LOVES this toy!
I recently purchased the Amazon Basics Hide and Seek Squeaky Dog Plush Toy, Rabbit and Carrot 5 Pack, and it has been an absolute hit with my dog Haru! This set has quickly become his favorite playtime activity, and it's easy to see why.
From the moment I introduced Haru to the plush toys, he was hooked! The rabbit and carrot design is not only adorable but also adds an element of excitement and curiosity for him. The toys' quality is impressive, with sturdy stitching that has held up well to Haru's enthusiastic play style.
The "hide and seek" aspect of the toys is brilliant. Each plush toy contains squeakers, which immediately captured Haru's attention. He thoroughly enjoys searching for the source of the squeaky sound and then triumphantly "catching" the rabbit or carrot. It's like a mini-game that keeps him mentally stimulated and entertained.
One of the best things about this 5-pack set is the variety it offers. Haru never gets bored because he can alternate between the different plush toys, and each one presents a new challenge for him. Whether he's "hunting" the rabbit or "nibbling" on the carrot, his excitement is contagious!
Furthermore, I appreciate how these toys keep Haru engaged for a good amount of time. As a busy dog owner, it's essential to have toys that can entertain him while I'm occupied with other tasks. The Hide and Seek Squeaky Dog Plush Toy accomplishes this perfectly, giving me some peace of mind knowing Haru is happily occupied.
