ARM Midpipe Upgrade for BMW 340i/440i

Overview

The ARM 340i Midpipe significantly improves the sound of your B58, giving it the aggressive exhaust note you're looking for from a tuned B58-powered BMW. Designed to amplify the power and sound of your B58, the ARM 340i Midpipe eliminates the two central resonators found in the stock 340i midpipe. By retaining the OEM muffler you still have the ability to control the volume of your exhaust. Switch your car into Sport Plus and enjoy the sounds of the upgraded B58 sing, or flip it into comfort mode to drive through the neighborhood.
