HIGHLIGHTS • Exotic Exhaust Sound• X-Pipe Design• Fits OEM Underbody Brace • SS304 Stainless Steel• Saves 15lbs Over OEM    PROFILE 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 Midpipe substantially improves 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 tame volume when you want to be quiet, or open the valves for maximum sound. ENHANCE THE SOUND OF YOUR S58 The ARM S58 Midpipe will not only increase the overall volume of your exhaust but also transform the sound into something truly unique from an ordinary G80 M3.  It will also make the exhaust burbles more audible even with OEM tuning.  The G82 M4 in the video below is equipped with both the ARM S58 Midpipe and ARM S58 Downpipes.  Pairing the ARM S58 Midpipes with the ARM S58
