Product Details

The factory exhaust system was designed to maximize horsepower while keeping engine noise to a tolerable level. While this is fine for the average consumer, it leaves much to be desired in the hands of the enthusiast. 

For those individuals dedicated to unlocking the performance and excitement in their BMW a powerful and loud exhaust system is key. With the ARMYTRIX Valvetronic Exhaust system, you can access that extra power from a beautifully constructed and highly capable system without committing to a snarling exhaust tone all the time. Simply use their exclusive OBDII dongle to pair with your smartphone and flip the valves open for all the glorious sound and power you want, or close the valves for a subtle stealth mode when you need. The best of both worlds, power and sound or comfort and quiet, allows you to control your driving experience behind the wheel of your BMW with ease from one of the most well designed high-flowing exhaust systems on the market.
