PROFILE

The ARM F80 M3 Downpipes are the solution for improving power, throttle response, and exhaust note on your S55 powered F80 M3. Our goal for the ARM F80 M3 Downpipes was to provide a solution that would maximize power and torque, fit perfectly, and sound extraordinary. The ARM F80 M3 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. Even with the Resonated ARM F80 M3 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 M3 will make under part and full throttle.

RUMBLE, NOT RASP.

The ARM Resonated S55 Downpipes give your F80 M3 an unparalleled sound that even other F80 owners will notice. Our 4" resonators are installed in the location to enhance the sound of your S55 without compromising the precise fitment of our F80 M3 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 F80 M3 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 ARM F80 M3 Downpipes feature a smooth, gradual transition from the 3" inlet to the 2.5" exit for optimum exhaust flow.
