The ARM F82 M4 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 F82 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 F82 M4 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 M4 will make under part and full throttle. RUMBLE, NOT RASP. The ARM Resonated S55 Downpipes give your F82 M4 an unparalleled sound that even other M4 owners will notice.The deep, aggressive tone of the ARM F82 M4 Resonated Downpipes will stand out next to the all too familiar high-pitched rasp of other catless downpipes.Our 4\\
