PROFILE

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.

CONSTRUCTION

The ARM 340i Midpipe will allow for fitment, sitting well within the recess for the exhaust underneath the vehicle. The ARM 340i Midpipe is designed to fit either the OEM downpipe, or any upgraded downpipe that fits the OEM midpipe. The ARM 340i Midpipe upgrade deletes the two OEM resonators opening up the sound of your B58.

IN THE BOX

• 1x ARM B58 Midpipe Front Section
• 1x ARM B58 Midpipe Rear Section
