The ARM S58 Midpipe upgrade is designed to unleash the incredible exhaust sounds from your G80 M3/M4. By removing the secondary catalysts and two middle resonators, the ARM S58 Midpipes substantially improve the sound of your S58 powered BMW. Also, by retaining the OEM muffler, you still have the ability to control the exhaust flaps, allowing you to close them for a more subtle tone for when you want to be quiet, or open the valves for maximum sound.
