PROFILE
The ARM F87 M2 Competition Downpipes are the ultimate solution for improving power, throttle response, and exhaust note on your S55 powered F87 M2 Competition. Our goal for the ARM F87 M2 Competition Downpipes was to provide a solution that would maximize power and torque, fit perfectly, and sound extraordinary.
Catless downpipes are considered a standard upgrade for any F87 M2 Competition owner looking to safely push their S55 engine beyond basic Stage 1 tuning. With Stage 2 and up tuning, higher boost increases back-pressure at the OEM catalysts and chokes the S55's turbochargers, causing them to work harder and shortening their life.
The ARM F87 M2 Competition Downpipes relieve the stressful back-pressure caused by high-boost tunes, allowing the exhaust to flow freely, increasing power and torque, all while extending the longevity of your S55's turbochargers. On our test car, after installing our F87 downpipes and switching to a Stage 2 flash we made 543whp and 547wtq, this is 73whp and 126wtq gain over the stock results!
Even with the Resonated ARM F87 M2 Competition Downpipes installed on your stock-tune S55, you will notice an increase in power, torque and responsiveness. Not to mention the incredible, head-turning sounds your M2 Competition will make under part and full throttle.
RUMBLE, NOT RASP.
The ARM Resonated S55 Downpipes give your F87 M2 Competition an unparalleled sound that even other F87 owners will notice. The deep, aggressive tone of the ARM F87 M2 Competition Resonated Downpipes will stand out next to the all too familiar high-pitched rasp of other catless downpipes. Our 4" resonators are installed in the perfect location to enhance the sound of your S55 without compromising the precise fitment of our F87 M2 Competition downpipes.
Alternatively you can opt for the catted version which replaces the resonators on each downpipe with a 200 cell catalysts to help reduce emissions.

CONSTRUCTION
Precision CNC machined v-band flanges offer a smooth transition of exhaust gasses from the the turbochargers to the ARM S55 Downpipes. The body of the 3" ARM F87 M2 Competition Downpipes are constructed of SS304 Stainless-Steel and are threaded smoothly and perfectly though the space given by BMW towards the mid-pipe section.
Any downpipes that bolt up directly to the OEM mid-pipes must reduce to the 2.5" to meet the size of the OEM mid-pipes. Some aftermarket downpipes use an abrupt, short reducer which causes turbulence in the exhaust gasses. The ARM F87 M2 Competition Downpipes feature a smooth, gradual transition from the 3" inlet to the 2.5" exit for optimum exhaust flow.
The ARM F87 M2 Competition Downpipes are a massive improvement over the OEM S55 downpipes, with precise fitment and brilliant finish the ARM S55 Resonated Downpipes are the perfect solution for your S55 project. Our goal for the ARM F87 M2 Competition Downpipes was to provide a solution that would maximize power/torque, fit perfectly, and sound uniquely extraordinary. We are so confident that you'll agree we've achieved this, we back every set of our ARM F87 M2 Competition Resonated Downpipes with a 30 Day Money-Back Guarantee and the ARM Lifetime Free-Replacement Warranty.

Feels heavenly
Size: King (20" X 36"), Color: 14 - Lavender - Zipper, Number of Items: 2
Literally just got it in the mail and fell in love. It's so soft and wasn't being harsh with my beard hair. Hopefully no more split ends! (Good hair protection!)
There was no odor to speak of and it fit my pillow perfectly, we got king size, (AKA good compatibility)

Super soft and worth it
Color: Light Grey, Size: 2 Pack King（20"X 36"）
Honestly really happy with these pillowcases. They feel super soft and cool when you sleep on them. My hair has been way less messy in the morning too. The quality actually feels pretty nice and the king size fit perfectly. Makes my bed feel a lot more comfortable and expensive looking. Definitely glad I bought them.
