Description

The ARM F80 M3 Downpipes are the ultimate 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.  On our test car, after installing our F80 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 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. 
 
The ARM Resonated S55 Downpipes give your F80 M3 an unparalleled sound that even other F80 owners will notice.  The deep, aggressive tone of the ARM F80 M3 Resonated Downpipes will stand out next to the all too familiar high-pitched rasp of other downpipes.  Our 4" resonators are installed in the perfect location to enhance the sound of your S55 without compromising the precise fitment of our F80 M3 downpipes.
