PROFILE


The ARM B58 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 B58 Midpipe eliminates the two central resonators found in the stock 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. 


 


CONSTRUCTION


The ARM B58 Midpipe will allow for perfect fitment, sitting well within the recess for the exhaust underneath the vehicle. It has also been engineered to sit at or above any other portions of the car, giving you adequate clearance, even if you're on a lowered suspension.

M240i Midpipe

The ARM B58 Midpipe is designed to fit either the OEM downpipe, or any upgraded downpipe that fits the OEM midpipe.  The ARM B58 Midpipe utilizes the OEM midpipe mounting location to secure the midpipe during aggressive driving.  

M240i Midpipe


The ARM B58 Midpipe is comprised of two sections, the longer front section and the shorter rear section.  The two sections of the ARM B58 Midpipe are joined with a slip-fit style connection and high quality performance-grade exhaust clamps.  The ARM 340i Midpipe upgrade deletes the two OEM resonators opening up the sound of your B58. 

M240i Midpipe

The ARM B58 Midpipe utilizes a full 3.25” system throughout, from the downpipe all the way to the muffler. 


IN THE BOX

• 1x ARM B58 Midpipe Front Section
• 1x ARM B58 Midpipe Rear Section
• 4x Exhaust Clamps
