MAD BMW G90 M5 H-Pipe Midpipe

Expected release date is Oct 5th 2026 MAD BMW G90/G99 M5 — H-Pipe Midpipe Introducing the MAD H-Pipe Midpipe for the BMW G90/G99 M5, engineered to unlock the true sound of BMW's twin-turbo V8 while maintaining the refined character expected from a modern M car. The factory midpipe heavily suppresses the exhaust note, leaving the S68 sounding quieter and more muted than it should. The MAD H-Pipe changes that by allowing both exhaust banks to communicate through a precision-engineered balance section, creating a deeper, fuller, and more aggressive tone without introducing unwanted rasp or excessive cabin drone. Unlike a single midpipe, the H-pipe preserves the classic dual-exhaust layout while enhancing the natural V8 rumble. The result is a richer exhaust note with improved low-end presence, stronger acceleration sound, and a more refined overall character that's perfect for both daily driving and spirited performance. Whether paired with the factory axle-back or the MAD axle-back, the MAD H-Pipe delivers a significant improvement in sound while maintaining excellent drivability.
