ARM Motorsports Upgraded Midpipe - B58 B58MID3

Upgraded Midpipe - B58

The ARM 340i Midpipe elevates the sound of your B58, delivering the aggressive exhaust note you've been looking for in a tuned B58-powered BMW. Engineered to boost both power and sound, this midpipe eliminates the two central resonators found in the stock 340i setup. Retaining the OEM muffler allows you to control the exhaust volume—engage Sport Plus mode to unleash the full roar of the upgraded B58, or switch to Comfort mode for a quieter drive through the neighborhood.
