The ARM M240i 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 M240i Midpipe eliminates the two central resonators found in the stock M240i midpipe.
Designed in house and tested on our own M240i, the ARM M240i Midpipe will allow for fitment, sitting well within the recess for the exhaust underneath the vehicle. The ARM M240i Midpipe is designed to fit either the OEM downpipe, or any upgraded downpipe that fits the OEM midpipe. The ARM M240i Midpipe uses the OEM midpipe mounting location to secure the midpipe during aggressive driving. The ARM M240i Midpipe upgrade deletes the two OEM resonators opening up the sound of your B58.
