340i GETS AN EXHAUST! - Louder, Lighter & Aggressive

Time to wake the neighbors. In this video, I install the ​⁠‪@ARMMotorsports‬ exhaust on my BMW 340i and show off the before and after with sound clips — revs + loading a launch to hear the difference. This system gave the car a deeper tone, quicker throttle response, and more attitude on the street. If you’re considering an exhaust upgrade for your B58, this might be the perfect aggressive setup.
