Product Description
The MAD axle-back is the perfect finishing touch for your G90 M5 especially when paired with the MAD 5-inch midpipe for maximum sound. Choose from brushed, black, or carbon tips to match the look you want.
This system features larger-diameter piping for increased flow, and it’s fully valved with two valve motors and a valve controller included. You have full control over your exhaust tone, allowing you to switch between a quiet, comfortable sound or a loud, aggressive tone whenever you want. The smaller muffler box reduces weight and improves airflow even further, delivering more sound, better throttle response, and a cleaner overall tone.
Deep, aggressive, and controlled this setup gives the G90 M5 the sound it should’ve had from day one.
