Description
Upgrade the sound, performance, and control of your BMW G90 M5 with the MAD Axle-Back Exhaust System, engineered to deliver a more aggressive tone, improved flow, and full exhaust valve control that the factory system does not provide.
Designed as the perfect finishing touch for the G90 M5, especially when paired with the MAD 5-inch single midpipe, this axle-back system transforms the driving experience with a deeper, more refined, and more aggressive exhaust note.
Unlike the North American G90/G99 factory setup that lacks valve functionality, the MAD axle-back introduces a fully valved system with included valve motors and a dedicated controller, allowing you to switch instantly between a quiet, refined driving mode and an aggressive, high-performance sound profile.
Built from premium 304 stainless steel, this system features larger-diameter piping for improved exhaust flow and a reduced-mass muffler design to help lower overall weight while enhancing throttle response and sound clarity. The result is a sharper, more responsive exhaust note with a cleaner overall tone.
Available with brushed, black, or carbon tips, this system allows you to customize the visual finish to match your build.
