Armytrix Valvetronic Cat-Back Exhaust System - G80/G82 M3/M4

Product Details

The factory exhaust system on your new M3/M4 is designed to allow just as much flow as is necessary to meet operational requirements and reduce noise that would drive away non-enthusiast buyers. For those of us dedicated to taking advantage of both the performance and auditory potential of our cars, a high-flowing and screaming exhaust system is an absolute must. 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 G8X with ease from one of the most beautiful, high-flowing exhaust systems on the market. Give your S58 the vocal upgrade it deserves while maintaining the theme of distinction with this beautifully constructed and wonderfully sounding ARMYTRIX Valvetronic Exhaust System.
