Premium Valve Control

The G90 M5 valved catback exhaust system allows drivers to control sound levels using factory M drive settings or the included valve controller.

Quiet when cruising and aggressive when desired, this system gives you full control over the exhaust sound of your BMW G90 M5 performance exhaust.
