B58 DOWNPIPES
The ARM B58 Downpipe is one of the foundational upgrades for giving your B58-powered BMW more power, torque, and sound. We offer THREE different versions of the B58 downpipe. Those versions include, 4.5in Downpipe, 6in Downpipe, and 6in Catted Downpipe. The stock B58 downpipe comes from the factory with a catalyst that severely restricts exhaust flow, causing excessive backpressure with increased boost. Upgrading your downpipe unlocks power, improves turbo spool, allows you to safely run stage 2+ tuning, all while increasing the sound of your B58-powered BMW.
B58 MIDPIPE UPGRADE
The ARM M240i/340i/440i 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/340i/440i Midpipe eliminates the two central resonators found in the stock M240i/340i/440i 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. You can select the ARM Single Exit Exhaust option to turn your ARM M240i/340i/440i Midpipe into a full 3.25" straight-piped system, for maximum volume and weight savings.
B58 SINGLE EXIT EXHAUST
The ARM M240i/340i/440i Single Exit Exhaust is the final step in your M240i/340i/440i exhaust modifications. This is for the all-in M240i/340i/440i enthusiast, seeking the lightest and loudest exhaust available. You will see significant weight savings and an engine note that SCREAMS.The ARM M240i/340i/440i Single Exit Exhaust connects to the end of the ARM M240i/340i/440i Midpipe, extending the 3.25" midpipe all the way to a passenger-side single exit tip.
