Armytrix BMW M3/M4 Cat-Back Exhaust System is a truly incredible system for the F8X platform, offering a noticeable power gain, weight saving and noise enhancement over standard.
The system has been thoroughly engineered to reduce back pressure, maximising air flow efficiency for better throttle response and faster turbo spool. It offers an upgraded valve system that is fully controllable using the Armytrix key fob, allowing you to take ownership over your vehicle's exhaust sound.
Crafted using high-grade aluminium, the system is highly resistant to corrosion and extremely durable in the long-term.
