RUMBLE, NOT RASP.
The ARM Resonated S55 Downpipes give your  F80 M3 F82 M4 and F87 M2C  an unparalleled sound that even other F8X owners will notice. The deep, aggressive tone of the ARM F8X Resonated Downpipes will stand out next to the all too familiar high-pitched rasp of other catless downpipes. Our 3" resonators are installed in the perfect location to enhance the sound of your S55 without compromising the precise fitment of our F8X downpipes.

IT ALL STARTS HERE
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 F80 M3 F82 M4 F87 M2C  Downpipes are constructed of SS304 Stainless-Steel and are threaded smoothly and perfectly though the space given by BMW towards the mid-pipe section.



THE FINISHING TOUCH
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 F80 M3 F82 M4 F87 M2C Downpipes feature a smooth, gradual transition from the 3" inlet to the 2.5" exit for optimum exhaust flow.


The ARM 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 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 Resonated Downpipes with a 30 Day Money-Back Guarantee and the ARM Lifetime Free-Replacement Warranty.
