BMW M2 F87 Active Valve Titan Sport System
The BMW M2 active exhaust is a lighter weight system that has more efficient flow and shows a noticeable improvement in throttle response whilst enhancing that sports car sound. The system is designed to work with the engine, so at lower revs the sound remains relatively civilised and at higher revs it provides more presence and volume. The system is fully valved so can be operated independently to the cars setting. A good sounding engine made fantastic.
