The BMW F10 M5 is one of the fastest sedans on the market. Its 4.4L twin turbo engine cranks out over 500 horsepower. Add in a ECU tune and the ARMYTRIX exhaust, you get a 600 horsepower monster! Vivid Racing shot this video of them testing out the Armytrix exhaust on the dyno and discussing how the iphone APP works to control the exhaust valves from quiet to loud. The full exhaust system includes downpipes and this one is finished with matte black tips. Check out the video and install photos below!
