PROFILE
The ARM S55 Downpipes are the ultimate solution for improving power, throttle response, and exhaust note on your S55 poweredM4. Our goal for the ARM M4 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 anyM3, M4, or M2 Comp.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.
